Question

what medium is required for a sound wave

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.

Answer 2

A medium is required in order for sound waves to transport energy. Mechanical waves require a medium in order to transport energy. Sound, like any mechanical wave, cannot travel through a vacuum
