Question

Explain in short how sound travels

Answer 1

Sound is a form of longitudinal wave. It travels by the compression and rarefaction of molecules of the medium.

Answer 2

Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium. In sound, the disturbance is a vibrating object. And the medium can be any series of interconnected and interactive particles. This means that sound can travel through gases, liquids and solids.
