Question

why sounds requires a medium to travel​

Answer 1

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.

It is bcoz without medium sound cannot travel as the molecules will not take up the vibrations and will not transfer it and alao then we cannot hear the sound.
