Question

Answer the following questions explain with the
diagram, medium is necessary for the propagation of sound ?​

Answer 1

Answer:-

Sound is a mechanical wave and propagation of mechanical wave is possible only when there is a medium. So medium is necessary for propagation of sound.

Answer 2

Answer:

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
