Question

which is required for the propogation of sound ?​

Explanation:

Sound needs a material medium for its 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.
