Answer 2

Question :-

what happen to the loudness of sound in vacuum?

____________________________________________________________________

Answer :-

Sound waves always require a material medium to propagate.

When a source of sound creates vibrations , the vibrations travel through a particular medium causing compressions and rarefactions in the medium.

If there is a vacuum , then simply the sound waves cannot travel through the medium because there will be no vibrations at all .

This is particularly because there is no material medium !

It is hence said that we cannot hear sound in vacuum.

Thus the loudness of the sound would be zero .

Hope it helps you :-)
