When source and detector are stationary ...

When source and detector are stationary but the wind is blowing at speed `v_W`, the apparent wavelength `lamda'` on the wind side is related to actual wavelength `lamda` by [take speed of sound is air as v]

A

`lamda'=lamda`

B

`lamda'=(v_W)/(v)lamda`

C

`lamda'=(v_W+v)/(v)lamda`

D

`lamda'=(v)/(v-v_W)lamda`

Text Solution

Verified by Experts

The correct Answer is:
C

`lamda'=(v+v_(omega))/(f)=(v+v_(omega))/(v)lamda`
