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.
Which requires a physical medium in which to travel light or sound?
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
What is needed for sound to travel?
Sound requires a medium to travel
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.
Can sounds travel in a vacuum?
No, sound requires a medium to travel.No it must travel through matter
Can you hear anything in outer space?
No. Sound requires a medium through which it can travel. Since space is near a vacuum, there is no medium for sound.
What speed does sound travel from the sun to the earth in mph?
sound requires a medium, such as air, to travel. Space is a vacuum, so sound doesn't travel from the sun to earth.
Do air particles travel with sound sound waves?
since sound needs a medium for its propagation , it requires air particles to travel along with its waves.
A wave that requires a medium to travel?
A mechanical wave such as a sound wave requires a medium to travel through.
Why light travel in vacuum but not sound?
Light requires nothing more than a source for transmission. sound requires a source and a medium to conduct it. In vacuum, there is no conductor for sound.
what vcan travel with or without a medium?
Light is a form of electromagnetic radiation that can travel through a vacuum, or a space with no air, meaning it does not require a medium to travel through. Other forms of electromagnetic radiation, like radio waves, microwaves, and x-rays, can also travel through a vacuum. Sound, on the other hand, is a form of mechanical wave which requires a medium to travel. This medium can be a solid, liquid, or gas, and is the way sound travels from one place to another. For example, when someone speaks, the sound waves travel through the air and reach our ears. In summary, light and other forms of electromagnetic radiation can travel with or without a medium, while sound requires a medium to travel.
