How Far Away Is Lightning? For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.

lightning strikes a tower 4 km away. how long after the strike will you hear the thunder? the speed of sound is 344 m/s If you hear thunder 36 seconds after you see a flash of lightning how far away is the thunderstorm? About 12 kilometers (7.45 miles). After you see a bolt of  lightning, for every 3 seconds until you hear the thunder, it means  it is one kilometer away (3 seconds = 1 kilom…eter). This is because  the sound wave created by the lightning is traveling at about 330  m/sec (in dry air, the speed of sound is about 343 m/sec or 1127  ft/sec).    You can also divide by 5 to determine the approximate number of  miles. In this case it would be calculated as about 7.2  miles away.

Lightning by the Numbers A typical lightning bolt is rated at up to 125 million volts. The “average” lightning bolt is very hot. 15,000° C (the surface of the sun is 6,000° C). Lightning bolts can travel 10 miles or more. Lightning strikes travel at 1,000 feet/second. Sound and thunder travel at 750 feet/second.

Lightning Distance Calculator The delay between when you see lightning and when you hear thunder occurs because sound travels much, much slower than light. Sound travels through air at about 1100 to 1200 feet per second (our default is 1150). That is a little more than one mile per five seconds. This approximation will give you a good idea of how far away the lightning was.

- The closer you are, the shorter the gap between the lightning and thunder. The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour). Thunder is difficult to hear at distances over 12 miles (20 kilometres).

- 4 miles away. 25 seconds after a Flash. 5 miles away. 30 seconds after a Flash. 6 miles away. 35 seconds after a Flash. 7 miles away. 40 seconds after a Flash. 8 miles away. Because lightning can strike up to 10 miles from a storm, you should seek safe shelter as soon as you hear thunder or see lightning. Get to a safe location if the time between the lightning flash and the rumble of thunder is 30 seconds or less.

How fast does lightning strike? According to Jerry Dennis, at the American Department of Energy, lightning bolts travel at speeds up to 93,000 miles per second. What we see as a single lightning flash is actually several lightning bolts that follow each other so rapidly that our eyes see only a single flash.t takes the stepped leader about 50 milliseconds (1/20th of a second) to reach its full length, though this number varies depending on the length of its path. Studies of individual strikes have shown that a single leader can be comprised of more than 10,000 steps!

Number of lightning strikes per year 138 million ground strikes/year worldwide. Specialists consider that there are approximately 2,000 thunderstorms around the world producing about 44 flashes of lightning each second. Needless to say, there is about 138 million ground strikes/year worldwide. It is interesting to know the fact that about 78% of the lightning strikes occur in the tropics. Needless to say, on average, all over the world, lightning strikes approximately 100 times per second. This is definitely something.

How to Estimate Lightning's Distance Since light travels at 186,000 miles per second, you see the lightning the instant it flashes. But sound, including thunder, travels about a mile in five seconds near the ground. If 15 seconds elapse between seeing a lightning bolt and hearing its thunder, the lightning was about three miles away. Lightning closer than about three miles away is a warning to take shelter immediately. Successive lighting strikes are often two to three miles apart.

- Avoid getting caught in a dangerous situation! If you can hear thunder, you are close enough to be struck by lightning! Myth: It’s not raining here, and skies above me are clear, therefore I am safe from lightning. Fact: Lightning can strike many miles away from the thunderstorm. If storms are in your area, but skies. happen to be clear above you, that certainly does not imply you are safe from lightning. Though these. “Bolts from the Blue” are infrequent, lightning strikes 10 to 15 miles away from the storm are not out of the.

How fast does lightning travel per second? Lightning is in fact not light. But as the electronic plasma moves through charged air, it releases light waves. Depending on air conditions, the typical lightning bolt moves at 224,000 mph -- or about 3,700 miles per second.However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.+ 125 others found this useful.ight travels at the speed of 186282 miles per sec. According to Einstein it is impossible to go faster or as fast as light because it requires an infinite mass. Right now Ein … steins word is law because there has been nothing to disprove him.

Lightning Safety for Outdoor Athletes If thunderstorms develop, count the seconds between the flash of lightning and the bang of the thunder to estimate the distance between you and the lightning strike. Because sound travels at approximately 1 mile in 5 seconds, you can determine how far away the lightning is by using this flash-to-bang method. It is recommended that you seek shelter if the time between the lightning flash and the rumble of thunder is 30 seconds or less (6 miles). Once inside shelter, you should not resume activities until 30 minutes after the last audible thunder. This is known as the 30/30 Lightning Rule.

Why Do Dogs Vomit White Foam? Yet another reason dogs vomit white foam is because of kennel cough, which is an upper respiratory infection that is contracted from other dogs. Dogs suffering from kennel cough have a dry cough and experience flu-like symptoms, such as nasal discharge, sneezing and fever. Finally, vomiting white foam is a sign of rabies as well. The foaming around the mouth is caused by nerve damage around the mouth and throat, which prevents the dog from swallowing.

What is the speed of lightning? Propagation of high-altitude lightning observed from space was measured at a speed of 50 kilometers per second (112,000 mph). This is considerably slower than the 670 kilometers per second (1,500,000 mph) maximum return stroke velocity reported in an IEEE report in 2006.

How Far Away Is That Storm? Lightning is over 40,000 degrees Fahrenheit. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by the rapidly expanding atmosphere. The purpose of this experiment is to watch lightning and hear thunder to give you clues about how far away you are from a storm. One thunderstorm. A stop watch (or the ability to say one-Mississippi) 2. For every 5 seconds the storm is one mile away.

How do I tell how far away a thunderstorm is? ( If you are frightened of thunder, it is useful to remember that by the time that noise has reached you, the really dangerous lightning strike has already occurred. Very roughly, the speed of sound in the lower atmosphere is 330 metres / second (or 1 mile / 5 seconds). If you observe the 'flash' of the lightning stroke, then begin counting (or timing) in seconds until the sound of the thunder just reaches you, using the relationships above will give a rough guide to the distance of the storm.
