Question

source of sound 500 Hz the move towards a stationary observer with a 30 metre per second with speed of sound observer frequency will be​

Answer 1

Given

n = 500 Hz

Vs= 330 m/s

v = 30 m/s

n'= ?

n' = n ( V/ V - Vs )

n' = 500 ( 330 / 300 - 30 )

n' = 550 Hz

Answer 2

Answer

Given; n=500Hz,Vs​=330m/s,v=30m/s,n′=?

n′=n(v/vs​v​)

⇒n′=500(330/300-30​)=550 Hz
