A sound wave of frequency f propagating ...

A sound wave of frequency `f` propagating through air with a velocity `C`, is reflected from a surface which is moving away from the source with a constant speed `V`. Find the frequency of the reflected wave, measured by the observer at the position of the source.

B

`(f ( c + v))/( c-v)`

C

`(f(c-v))/( c+v)`

D

`(f ( c-v))/( c- 2 v)`
