- The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone. For more modern phones that have a telephone answering service, the sound wave is captured on a recording device which allows for the operator of the phone to playback at a later time.

Why won't sound travel in a vacuum? Any sound waves use a medium to travel along (on Earth the medium is Air, Water or any Solid. A Vacuum, like Space, does not contain any particles; therefore sound waves have no medium through which to travel and thus Sound will NOT Travel (or be heard).

How does sound travel? It is a wave which is created by vibrating objects and propagated through a medium (solid, liquid or gas) from one location to another. A vibrating source can be sound coming from a drum, speaker of a radio, the mouth of a person (vocal chord), a car engine, a plane above the sky and so on.

- Sound waves travel through air in much the same way as water waves travel through water. In fact, since water waves are easy to see and understand, they are often used as an analogy to illustrate how sound waves behave. Sound waves can also be shown in a standard x vs y graph, as shown here.

""" Are cold sores the same thing as herpes? """ There are numerous different types of infections that the herpes virus can cause, and they are typically grouped by the locations of the infection. For instance, the classic cold sore is usually due to a Herpes labialis (or Herpes lip) infection (Most commonly with HSV1). Whereas genital herpes obviously involves the genitals (and is usually due to HSV2).

- Sound can only travel through a material. It will travel through air, through walls (and other solid objects), and through water and other liquids. On the other hand, a light wave is not made of vibrating particles. It is a wave of changing electric and magnetic fields which can exist in a vacuum.

How Hearing Works Catching Sound Waves. We saw in the last section that sound travels through the air as vibrations in air pressure. To hear sound, your ear has to do three basic things: 1  Direct the sound waves into the hearing part of the ear.2  Sense the fluctuations in air pressure. 3  Translate these fluctuations into an electrical signal that your brain can understand.e saw in the last section that sound travels through the air as vibrations in air pressure.

Mimicry We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal. The first person to discover that sound needs a medium was a brilliant English scientist known as Robert Boyle (1627–1691).

Lightning Sound travels through air at about 340 m/s. An observer can approximate the distance to the strike by timing the interval between the visible lightning and the audible thunder it generates. A lightning flash preceding its thunder by five seconds would be about one mile (1.6 km) (5x340 m) distant.

- Space is a very quiet place. But sound doesn't have to move through air-it can just as easily move through water, or through metal wires. In fact, sound moves faster through water than it does through air. But whether in air or in water, sound moves much more slowly than light does.

- Sound waves in air are longitudinal waves, in that the pulsating motion of the air is in the direction the sound wave travels. Physicists classically demostrate this with the Slinky model, in which a quick push on one end of a slinky will cause a longitudinal wave to travel down its length.

All About Salt Celtic Salt: this is a sea salt that contains all of the trace minerals and more and it is grey and clumpy. You can certainly find it at most health food stores. Black Salt: this is an example of an unrefined salt that is not tasty. It smells like sulfur and is pink in color.

Electronic Sound Reproduction After the microphone detects the sound, it goes through some electronics and is then reproduced and transmitted through loud speakers or headsets that consist of tiny speakers. Just like a microphone, the speakers also attenuate various frequencies and distort the sound coming out.

Sound The matter that supports the sound is called the medium. Sound cannot travel through a vacuum. Longitudinal and transverse waves. Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.

- 1 A perfect example of this is satellites orbiting in outer space. They transmit radio waves through space to antennas here on the ground.).  Sound travels at approximately 1,100 feet per second (766 miles per hour). Radio waves travel at the speed of light, which is approximately 186,000 miles per second.

- The diaphragm presses against these carbon grains. Low voltage electric current travels through the grains. This current comes from batteries at the telephone company. The pressure on the carbon grains varies as sound waves make the diaphragm vibrate. A loud sound causes the sound waves to push hard on the diaphragm.

Sound Energy How does sound travel? Vibrations from sound source cause the surrounding air molecules to move back and forth. What term is given for air molecules are pressed together when the vibrating object moves forward and compacts the surrounding air?

Ask Us Sound is caused by pressure waves in air (or something else, sound can go through water, for example). If there is no material (called a vacuum), there is no way for sound to travel, so you can't talk. Inside a space capsule or space station there is air, so the astronauts can talk there. Dr. Eric Christian.

Sound 1 The study of sound should begin with the properties of sound waves. 2  Sound propagates through air or other mediums as a longitudinal wave, in which the mechanical vibration constituting the wave occurs along the direction of propagation of the wave.

- Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly as solids. And gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air. This is why whales can communicate over huge distances in the oceans. Sound waves travel about thirteen times faster in wood than air. They also travel faster on hotter days as the molecules bump into each other more often than when it is cold. Learning outcomes. The students will: identify mediums that sounds can travel through and classify them from slowest to fastest.

Q & A: Does light travel forever? First, let's think about why sound does not travel forever. Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). As the particles in the medium vibrate, energy is lost to heat, viscous processes, and molecular motion.

- Description. This clip is an investigation into how sound travels through solids. It uses a team of dancers and an experiment with a string telephone as an example. Sound can travel through some solids better than it does through air, because of the way the particles are close together. We also take into account the surface area of the solid.
