Question

Explain with a help of an experiment how sound is propagated through the medium of water.

Answer 1

Sound waves are longitudinal waves .
They propagates through water and air in the form of compressions and rarefractions.

We can take the example of a spring with very small force constant.

:- When we pull the spring from both sides and then push one of its side towards other a region of compression is formed which travels through the spring.
The same way sound propagates...
