Question

An observer moves towards a stationary source of sound of frequency n . The apparent frequency heard by him is 2 n . If the velocity of sound in air is 332 m/sec, then the velocity of the observer is

Answer 1

Answer:

hope the answer will help you

Answer 2

Answer:

Give is:- n=2n, no=n, v=332m/sec

Explanation:

An observer move towards a stationary source. So, n=no (v+vo/v) Let, put the value, we get vo=332m/s.
