Good. All right, guys, look, we're really excited about how things fell today. We wanted to come in and get better, and we did. We added four good football players. We added size, speed, athleticism, toughness, makeup, football IQ, everything we value. We added to this team in every phase, all three phases. Starting with Ebba-Cady, call him AK. We're excited. The reason we traded up is we had him high on the board, and we said we wanted to go up and get him. And so we gave up that fourth, and we're excited. We added a pass rusher that can win a lot of different ways. He's got variety. He finishes. He plays with the motor, and he's got top makeup. So he's going to fit in here. He's going to come here and go to work. Troy Anderson, man, excited about that player. You look at his measurables, size, speed, athleticism. He obviously has a unique background. And high football IQ, the things he can bring to this defense, we're going to be more excited. Again, makeup skill set. Then we get to Desmond Ritter and big athletic makeup, traits, tools. Very excited. He's obviously excited to be here. And then DeAngelo, the local, excited about him. When we brought him in to visit, we told him we had a feeling that he was going to be a falcon. He's going to be able to play for the home team. And he is another pressure player that plays with violence and toughness, any game you put on. So very excited about that group. Charles? And as we talked with Desmond, as you said, it was very exciting. One thing that he stressed was how excited he was to be with Marcus Marriota, who he said he compares himself to and others have compared him to. I was curious for Coach Smith, do you see cops from your time with Marcus before? Well, they're both very athletic quarterbacks. So that's a good thing that he's looked up to Marcus, because it'll be a really good room. Obviously, with Marcus, when he's talked to you guys, he's expressed over how excited he is for the opportunity. We had a competition, certainly. But that's at every spot. So Marcus being the veteran, it gives us a chance as you go forward. But again, as always, with any position of the team, the best player is going to play. But obviously, Marcus being the vet, that's the way it'll go starting out. Nothing's ever written in stone. We understand that. And when you have the right guys, that's how that room works, especially where we're at right now, currently, with our program. Josh? This is for both of you. Was Desmond a guy you felt like you could get at 74? Did you more feel like he fell in your lap and you've got to take him at that point in the draft? I'll say we stayed true to the integrity of the board. And we don't want to reach at any points. That's Scotton Department led by Kyle Smith, working along with the coaches in a collaborative effort to a great job setting that board. And we stayed true to the board and took the best players off. And he was meant to be there at that time. And we're excited to make that call. You surprised he was there at 74? I mean, I know that that's good for storytelling and whatever surprise.  I mean, there's just so much. When you look at everything now, everything's covered now. Like, what's really true about that? That's why you've got to a tariff point. You can stay disciplined to the board. There's a lot of good players on there. Reverend Draft, it's a heck of an opportunity to come in here and compete. We're certainly happy with all of them. We're happy. D'Angelo Malone was where he was. So it's just, I have a hard time saying, surprised. We stayed disciplined. And obviously our scouts did a hell of a job and knocked it out of the park. And it pretty much fell the way we expected. And so that's what you want. You're never going to be 100% because everybody's got a lot of different styles and flavors that they value. But we're so excited about the four guys we drafted here tonight. I know you're not surprised by anything, but quarterbacks were viewed a certain way in this league. Were you surprised that there was not a quarterback taken, really, until you guys took Desmond down? No, I'm not curious. Kyle, again, you're trying to go with the narrative about, I understand what you're saying. Mike, you ever want the sensation of this, oh, wow, quarterbacks dropped. There's guys, go back to history of this league. There are guys you've taken.  And you never know certain people's needs, the way it falls. There's obviously a run on certain positions. You see that happen all the time. As a value of certain positions, you see a run on receivers. You see a run on passers, you see a run on corners. That's not a knock at any other position. So again, nothing surprised me.  And we're excited as hell about these four players we added tonight. When you look at Troy Anderson, weird. I mean, I'm guessing it starts at linebacker for him, right? But like, weird, do you see the type of player when you look at him, you're like, oh man, there's so much I theoretically can do with him here? Or do you see him really strictly as a linebacker? Well, I'd say strictly. You're asking if we're going to use him a quarterback? No, not a guy. They said that on TV. Someone said that. Now, we had good background on him, not only from the scouting side, but from the coaching side. Mike Petrie was with him early in his career. So he's a rare athlete, a guy that's just, obviously, clearly, like when people say, oh, that guy's a football player, the guy's got great instincts, played multiple spots, he's got great spatial awareness, certainly his measables are off the charts, but you don't take the eyes of just on measables, the guy can play. We feel good about the competition in that room, right, with Roshan. You bring Troy in there. You got Mike Walker in there. I mean, there's a good competition in that room. Jeff. Obviously, you went into the strap with a certain number of picks and everyone's always going to freak out or have a narrative based on your first pick. What happened yesterday? Last night, you guys took a wide receiver or everybody was like, you've got to fix the defense, maybe we need linemen. Today, three of your four picks were on the defensive side of the pole. All tough guys, a couple edge rushers. Do you think you somewhat sent a message that, and I know this isn't your number one objective to quite answer anything, but about what you want here and you know what you need to do there? Well, what I would say to that, Jeff, is we don't progress over perfection, right? We're not gonna, it's one bite at a time.  And so we want to add one player at a time. So it could have failed to where we got two offensive players in the second round and we would have been fine with that because that's how the board failed and we know we're not solving all the problems, right? We're doing it one player at a time and we're focusing on the process. And so when you're focusing on that, we're not even thinking about anything on the outside. We're bringing in good players one player at a time. When we got into that second round, we're sitting down this morning and okay, we want to go get AK. If he's there, we're going to get him. And that wasn't because we hadn't taken a, we didn't take a defensive player in the first round. That's because he was the best player on that board. And in the same, when we got down to Troy and we were excited he was there, but it could have been another, if it was an offensive player, we'd have been fine with that. One player at a time and it couldn't have fell any better. We're excited how it fell to us, but we're not trying to reach in any spot. And Arthur, can you just sort of add an ad in terms of the type of team that you want to build in terms of toughness, physicality?  How do you want us to? So you want a fast team, go get some fast players.  You certainly can push guys and enhance the development, but again, then my experience, if you don't have a strategy and then you actually don't go and implement it, you're just fluff, right? So there's certainly a theme to the players we drafted, but we felt good about it, whether that had been an offense or defensive player and it really worked out well. And that's why Terry and I both up here, how good of a job our scouts did. So our strategy as it fell, really worked well for us tonight. And certainly it helped too that there were positions of needs. Can you say it? We need it everywhere. We have needs everywhere. That's not a shot of anybody coming on a roster. It's just where we're at with the building process. So, yeah.  Simple as that. Yeah, coach. Desmond talked about the meeting in Cincinnati and pro day. What did he do to impress the massive entourage job We took an entourage everywhere. Do you like? No, I was looking a little bit deeper that day. Why? Yeah, just opt. It's been with what camera angle got you, right? So, no, that's what you want. No different than we sent, if you want to use the word entourage, Terry's entourage, we went out to LA. We went to Cincinnati. We're fortunate to be able to work on an organization that allows you to do that. Des, he's made of the right stuff too. We got a lot of good background on him. Obviously, he watched the tape. He saw what he did in that program in Cincinnati. He felt very comfortable with him when you see him and when you got to meet with him in person. I got a ton of respect for Luke Fickle in that program in Cincinnati. It's really impressive what they do and the way their culture is. And that guy, Des went in there and he won. And he'll come in here and he'll compete and he'll do the right things. And like I said, D-Led, we're excited to bring a player like that in here. Do you approach you on the board there too? You said you have meetings. Yeah, it's all part of it. It's all part of it. You want to check all the boxes, right? You're going to have the interviews, the times you get at the combine, and whatever exposures you get to them at the senior ball.  A lot of people can go in there and they can fake it for 15, 20 minutes. And you just keep gipping away and put all the pieces together. But it's certainly an important part of the process. But it's not the only part. I guess the best way to put it. And it was cool without those restrictions, being able to go out and being able to take everybody and all the places. And before that pro day, we got to meet his family and I got to talk to his mom. And you could, you feel it from her and she's competitive. And he wasn't highly recruited coming out. And you had a little chip on his shoulder. And so, but getting to talk to, you really get to know those players when you get to get around their families and those things. And you see that they're wired the right way. I don't know if y'all got to meet Drake's family while they're here today. But his father, his mother, Juan and Cindy. I mean, great people, his sister. Like you see what they really come from and why they are the men that they are. So all those exposures are really important. Being able to bring everybody, it's really important. I'll deal it out. I'll add a little quick story. I think it's kind of funny, but it didn't move the meter for us.  So they have a connection as small as the world is sometimes. And so, but that didn't move the meter either. But it was a good job, I applaud the effort by him. And we can find a copy of that. I may have to look on eBay tonight. That's still up and going. The worst part is, I won't tell it for it. I'll do it off the record later. I'll do it later. Are we just kind of chatting with Dez and seeing pretty mature, four-year starter, curious where you see maybe his development and his game as a QB right now? Well, like all these guys there's always things to work on, but he certainly has played a lot of good high-level football. And there's things we'll come in here and ask him to do.  When you're putting game plans together, it is refreshing. Because a lot of times, if you've got guys with very different skill sets, you're gonna have to have a plan. This guy goes out, here's where we have to go. So they're both really, you say, all three of them, Felipe too, Felipe's obviously built multiple position for us, but that part is nice. When you're putting it together and how we're gonna play, that part does help when they have similar skill sets. I don't know if both of you guys know you follow your board, but I thought it was interesting. Draft with a guy from Western Kentucky, Montana State. It says tonight he's not super small, but smaller school. What does that tell you maybe about your scouting process and finding guys maybe everywhere, maybe different than just traditional big schools? Yeah, I think the staff does a nice job and we don't discriminate. We're in every school and going through players, if you can play football, we're gonna find you. And it says a lot about the coaches as well, that hey, we're gonna dig and we're gonna stick to the process. When you stick to the process, there are good players in a lot of different places and we have a staff that's gonna work hard and find them. Part of that too, it is refreshing to some of those guys who are at the All-Star Games, right? The four of those guys that today they were all at the senior bowl. And so it helps, it's all part of the process. Your air scouts, guys that go over the top of them, you bring them in, they got the meetings, but then you get down to the senior bowl and you get exposure to them there. And it's not just because of when the senior bowl is why I draft them, but it is nice when you're able to evaluate that as part of the process as well. Yep. Josh? Terry, I'll stop your head. Can you remember a guy who had a resume like Anderson going back to high school and just, it's like a comic book character? I'm sure that's a compliment, right Josh? Yeah, I mean, yeah. Super, super, super, super, super, super, super. Well, let's not put that, let's not do that to Troy yet. Three state titles and valedictorian in high school, you know, started at three positions in college. You just, you know, obviously it's Montana State and Montana High School, but do you remember a guy who had those kind of accomplishments? That's a good question. And I can't think of anything like that right now. But it just, again, it goes back to the body of work, right? You're betting, you've got a very solid idea that he's got to go out here and prove it in the National Football League, but it gives you a lot of comfort and that, you know, you kind of know the character you're getting. Doesn't mean it's necessarily all of a sudden he's, but he's got the right makeup. He's been consistent in his life. He talks about accuracy and decision-making rate comes to the quarterback. It's kind of like the two, the two first lieutenants. What was it that you saw at a Desmond, maybe versus some of the other guys who were, I'm not going to compare it, but what would you see at a Desmond than that? We like his skill set. We like his leadership qualities too, right? So he's played at a high level. It's impressive what that program did. And like all these guys, when you get them, I mean, there are certain things they may have asked of, they've been successful in college and that's how part of his coaching, you know, to enhance some of those skills and the mental makeup of them, I thought his decision-making, I thought he had a good feel in the pocket and there's a look up a little minor technical things that you can always work with the quarterbacks. So that's what gave us a lot of comfort. Was there a specific, maybe stretch of games that he played that really like sold you on that from the tape or? I mean, I think that, you know, the ones that you look at that are certainly impressive as what they did when they went to South Bend, but he was very consistent. Charles, Terry, you've been very consistent today and yesterday about how well it committed you or to stay true to the board. But you said a few days ago, I'm looking at a quarterback, you wanted to add to the quarterback room, whether it be in draft three agency or a trade. Did you have a preference of those options to have somebody from this draft add it to that quarterback? No, no. And it's funny when I said that and I said, we could come out of this draft to the quarterback we could trade for quarterback we could. And I started getting texts when I walked out that we were trading for certain guys. And then obviously I saw a report that we were.  I didn't, there was never a time where me and author said, we have to come out of this draft for the quarterback or we need to, we didn't. We really stayed true to the process and stayed true to the integrity of the board. We really did. And he was the best player at that time. And that's why we took him off the board. We had it stacked. So there was never a time where we said, we got to, we got to get it. If we were to come out of this draft and it wouldn't have fell that way, we wouldn't have got a quarterback. We're excited that it fell this way. We're excited that Desmond's here though. When you're keeping those options open do you feel has obligated to make calls to explore trade possibilities that have been widely discussed in the media or for veterans or do you not pursue that? We're never going to close any doors at any position. We're always, we answer every call and we explore every opportunity. One thing too, I just want to put context to this because we talk about playing this with the board just the one thing, and I feel like I need to address this because what you're saying to the board doesn't mean if you got five left tackles there, you're going to take a five in a row. That's the one thing. I just want to put that guy, I shouldn't have to but sometimes you need to. So when you say to the board, and we talked about before like, things being even, sure. Yeah, there's a long way to go. But we're not going to sit there and draft seven corners in a row. Unless they're all the highs. Yeah, and I probably wouldn't show up to this problem. The offices are going to draft seven corners. They're the right ones. First of all, you drafted a second guy who gave himself a nickname. I don't know if you're aware of that. Like I said, it's actually refreshing. You talking about the doctor? Yeah, the doctor. Max told us that. Max Blank told us that he said he calls himself the doctor. That's great. And he wrote, he's writing it all down. Keeps things fresh. It does.  So you're looking for new material. He's got the doctor, we got the twin towers. That's beautiful. I'm glad. I hope some of them made great predictions too. Those are always fun to ask about. I'm sorry, you also got some three guys who will play basketball in some one line on your feet. Yeah, what's the Grizzly score right now? We got that. What was that? The Grizzly score? You knew it was close to our first half. Yeah, nobody knows. Yeah, no, it helps. Yeah, multi-sport guys with athletes. When somebody drafts a quarterback in the first round, everyone's going to drive right. Right. Quarterback in the future, quarterback. So what should people say or think when you draft a quarterback in the third round? Well, I mean, still, obviously, it's got an opportunity. Just because you're a first rounder doesn't mean you're going to make it. I mean, there's a graveyard full. And that's what history will tell you. It's got to be the right guy, the right fit, right system. Certainly, you've got to acknowledge when you take somebody super high, like you're talking about in the first round, there is a pressure to play them sooner rather than later. I think most places are in a position where they don't have that flexibility to sit behind a breath forward, right? So it's a heck of an opportunity. It's got to be the right system, the right fit, the right environment. And I think what we provide here for Desmond is that. And so we'll see what happens. But we're excited to have Marcus, too. So like I said, Marcus is a veteran. He's got experience. But with any position here, we have competition. It certainly helps. And the best guys will always play. Author always says that to the players. It doesn't matter how you got here. First round, second round, third round, fourth, fifth, sixth, seventh, or eighth. It doesn't matter how you got here. It doesn't matter how much you got paid when you come in. It's a competition at every spot. And the best players are going to play. Wool was about three. It was six minutes left. What's that? 94, not 10. Wool was about four. He was six minutes left. I appreciate that. I've got a chance to catch the end of it. Hopefully, John and the guys pull it out. I was going to say, do you have a small TV off on the side? I did not. I talked about it with Bassey, but I couldn't. I got to do my job. I wouldn't have been doing my job, I'd be. Any else? Thanks, guys. Appreciate it. Appreciate it, man.


So, now that we have learned about X-rays is the time to practice few problems. So these couple of problems I have taken just to let you know what kind of questions could come. So, after you watch these videos please make sure you try at least 20 to 30 problems on your own. So, here is the first one. It says that a potential difference of 1000 volt is applied across X-ray tube. So, this is a potential difference between the cylinder and the copper. The ratio of the D Broglie wavelength of the incident electron to the shortest wavelength of the X-ray produced is what? Now, shortest wavelength of the X-ray will be produced when entire energy of the electron gets converted into a photon's energy. Because one electron can only create one photon, so if entire energy of one electron gets converted into one photon's energy, that is what the maximum energy is and if photon energy is maximum, frequency will be maximum and if frequency is maximum, wavelength will be minimum. So, for minimum wavelength we have entire kinetic energy which is E times V. Electron E is accelerated through a potential difference of V, so kinetic energy will be E times V. So, E times V will be equal to H C by lambda minimum. So, this will give us minimum wavelength equals to H C by E times V. So, this is the minimum wavelength of the photon. Now, let us try to find out what is the D Broglie wavelength of the electron. Now, D Broglie wavelength of an electron is given as what? H by momentum P. Now, momentum is not given but what is E times V? It is the energy. What kind of energy it is? It is kinetic energy. So, if kinetic energy is given, can I find out the momentum? Momentum can be written as 2 times m into kinetic energy under root of that, because kinetic energy is half mv square, so if you multiply 2 times m with half mv square, it becomes m square v square. So, take under root of that, you will get m into v which is momentum. So, D Broglie wavelength of the electron will become H by under root 2 mk. And what is K? K is E times V. So, we will get this as under root of 2 into mass of electron into charge of electron into V. So, this is D Broglie wavelength and this is minimum wavelength of the photon and the ratio of this to this is asked. So, now you can solve this your own. So, this is how you solve this particular question. So, here is the next question. In this question, what is given is K alpha wavelength and L alpha wavelengths are given. We need to find wavelength of K beta. So, let us call this as lambda 1, this as lambda 2 and this as lambda 3. What comes in your mind? That formula comes, that formula says 1 by lambda is Rieckberg constant z minus b whole square 1 minus 1 by n 1 square sorry and minus 1 by n 2 square. This comes in your mind. What is K alpha? K alpha is a radiation when electron transitions from second orbital to the first orbital. So, n 1 is 1 and n 2 is 2. So, 1 by lambda 1 is Rieckberg constant z minus b whole square 1 by 1 square minus 1 by 2 square like this. What is L alpha? L alpha is a radiation when the electron transitions from third orbital to the second orbital. Isn't it? So, 1 by lambda 2 is Rieckberg constant z minus b whole square 1 by 2 square minus 1 by 3 square. So, we need to find what is lambda 3? Essentially, I want to find out what is lambda 3 in terms of lambda 1 and lambda 2. So, let me first write down the expression for lambda 3 also. So, lambda 3 corresponds to K beta radiation. What is K beta radiation? It is a transition from third orbital to the first orbital. So, this is Rieckberg constant z minus b whole square 1 by 1 square minus 1 by 3 square. Isn't it? Now look at these three equations carefully. 1, 2 and 3. What do you think is a relation between lambda 1, lambda 2 and lambda 3? If you see closely, if you add 1 and 2, if you add 1 and 2, you will get equation number 3. Isn't it? This thing will get cancelled out when you add these two. So, you will get this equation. Right? So basically, what you get here is 1 by lambda 3 is equal to 1 by lambda 1 plus 1 by lambda 2. So, this will give me lambda 3 as lambda 1 into lambda 2 divided by lambda 1 plus lambda 2. So, this is the answer. So, in this question, we have learned a very important thing. Apart from the problem, this problem, what we have learned is that you do not need to find out, you know, do not substitute the value of Rieckberg constant and try to get right hand side. Okay? First you get what is asked in terms of variables. So, unnecessarily you will be putting value of R here and multiplying with this. Isn't it? But if you look at closely, you will get a very nice expression between lambda's. Okay? So, you can directly get lambda 3 as lambda 1, lambda 2 by lambda 1 plus lambda 2. So, you do not need to substitute value of constants and n 1 and n 2 like that. Okay? So, this is how you solve this particular question. We will take another question. Alright? Okay? So, let us solve this question. In this question, we need to find out frequency of k alpha line for z equal to 57 if frequency of k alpha line of z equal to 21 is given. Okay? So, what is given is frequency of atomic number 29 for k alpha and we need to find frequency of z equal to 57 for k alpha. Fine? Now, again, that we will start with the basics. 1 by lambda is Rittberg constant z minus 1, 1 by n 1 square minus 1 by n 2 square, right? For k alpha, n 1 is 1 and n 2 is 2, right? So, we will get 1 by lambda is 3R by 4, sorry, this is z minus 1 square. Screening constant has a value of 1 for k. Okay? So, 3R by 4 z minus 1 whole square. Fine? So, it is frequency that is given. So, I will multiply c both sides. So, c by lambda is 3R c by 4 z minus 1 whole square, right? This is the frequency. Okay? So, this will give me frequency for z equal to 29 is equal to 3R c by 4 29 minus 1 whole square. Fine? Similarly, when you put z equal to 57, you will get frequency for z equal to 57 equals to 3R c by 4 57 minus 1 whole square, okay? And when you divide left-hand side and right-hand side, this constant will go away. So, you will get frequency of z equal to 29 divided by frequency of z equal to 57 is equal to 28 square by 56 square. Okay? So, if you know this, you will get the value of frequency for z equal to 57 for k alpha radiation. Okay? Fine. I want to take a pause here and, you know, also touch base on few things. For example, here one more thing which you could have used is Mousselie's law, which says that root of frequency is some constant c into z minus b. Okay? We have derived this Mousselie's law for k radiation. Okay? What about for other type of radiation, l alpha, l beta and things like those? So, if you see that 1 by lambda is Rigberg constant z minus b whole square 1 by n1 square minus 1 by n2 square. If I multiply c both sides, I will get frequency equal to Rigberg constant c into z minus b whole square 1 by n1 square minus 1 by n2 square. Okay? Now, here Rigberg constant c and 1 by n1 and 1 by n2. Suppose n1 and n2 are fixed. We are talking about transition between two fixed shells. Right? So, again you will get from this, you will get z minus b is equal to some constant into root of frequency. Right? Or you can write it like that also. If you take c left hand side, you will get root of frequency is this. Okay? So, constant remains constant, right? 1 by c is, we can say, c1. So, this Mousli's law is true for any kind of characteristic wavelength for the x-ray. Fine? It is not just for the k. So, you could have used Mousli's law here as well. Root of frequency of first k alpha, sorry, first atomic number that is 29, root of that divided by root of frequency of this atomic number's frequency is equal to z minus 1, which is 28 by 57. So, when you square it, you will get the same equation. This by that is equal to 28 square by 56 square, that's the only thing, that's the same thing which you will get. Okay? So, this is all about the x-rays. Hope you like the video and make sure once you watch this video, you have to practice at least 20 to 30 questions to get comfortable with it. Okay? Thank you.
