The famous bell jar experiment establishes that a material medium is so essential for sound waves to pass through. An electric bell is covered by a jar. The air inside the jar can be removed by means a vacuum pump. As the pressure inside the jar gets reduced the intensity of sound goes on decreasing and when the pressure becomes very much lower then no sound is heard. Thus the need of material medium for propagation of sound energy has been verified.

What factors are necessary for a sound wave to travel through a medium?
well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
Why cant sound travel through outer space?
Sounds requires a medium to travel through. An example is air. You've also heard sound travel through water and solid objects like wood. In the past it was often thought that no medium exists in space. However, in current astronomy and astrophysics it is thought that dark matter is the medium by which sound can and does travel about space. Due to the atoms being so spread out though, the human ear would not be capable of detecting the sound waves.

What does sound need to travel through?
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
What is the difference between sound waves and electromagetic?
Sound waves requires a medium, electromagnetic waves do not. Sound waves are longitudinal waves, electromagnetic waves are transverse waves. Sound waves Travels at approx. 330m/s in air, electromagnetic waves travel at approx. 3 x 10^8 m/s.
What types of materials can sound not travel through?
Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.
What is needed for sound to travel?
Sound requires a medium to travel
Which requires a physical medium in which to travel light or sound?
Sound requires a physical medium, such as air, water, or solids, in order to travel because it propagates through vibrations of particles in the medium. On the other hand, light does not require a physical medium and can travel through empty space as electromagnetic waves.
Sound can travel through a vacuum is it true or false?
False. Sound requires a medium, such as air, water, or a solid material, to travel through. In a vacuum where there is no medium, sound cannot travel.
Does sound travel in vaccum?
No, sound cannot travel in a vacuum because it requires a medium (such as air, water, or a solid material) to propagate. In the absence of a medium, there are no particles for sound waves to travel through, so sound cannot be transmitted.
What is required for sound to travel?
Sound requires a medium to travel through, such as air, water, or solids. It also requires a source of vibration or disturbance, such as a vibrating object or a sound wave. The vibrations create pressure waves that travel through the medium, and when those waves reach our ears, we perceive them as sound.
When is uni-lag pedIgree form coming out?
since the sound requires a medium to travel through. so the air is one of the medium for sound to travel. Therefore sound can travel through air.
What is sound an example of?
a mechanical wave that requires a medium through which to travel.
Which can sound NOT travel through?
Vacuum as sound needs badly a material medium to get it propagated.
What is necessary for sound to travel from one place to another?
Sound requires a medium through which it can travel, such as air, water, or solid materials. When an object vibrates, it causes the particles in the medium to vibrate, creating sound waves that travel through the medium. The speed of sound in a medium depends on its properties, such as density and elasticity.
Can sounds travel in a vacuum?
No, sound requires a medium to travel.No it must travel through matter
Does sound travel up or down in a vacuum?
Sound does not travel in a vacuum because it requires a medium, such as air or water, to propagate. In the absence of a medium, there is no material for sound waves to travel through, so sound cannot travel up or down in a vacuum.
Why sound doesnt travel in vacuum?
Sound requires a medium, such as air or water, to travel through. In a vacuum, there is no medium for the sound waves to propagate, so sound cannot travel. This is because sound waves require particles to vibrate and transmit the sound energy.
