Question

give reason= why can the sound not travel through vaccum​

Answer 1

Answer:

Sound waves are mechanical waves. Unlike electromagnetic waves, they require a medium to propagate.  Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work on it.

Answer 2

Answer:

Sound is a mechanical wave and mechanical waves are propagated by the oscillation of molecules in a medium like, air, water or gas. There are no molecules in the vacuum to produce oscillations. So sound cannot travel through vacuum
