The observer is moving with velocity 'v'...

The observer is moving with velocity `'v'_(0)` towards the stationary source of sound and then after crossing moves away from the source with velocity `'v'_(0)`. Assume that the medium through which the sound waves travel is at rest. If v is the velocity of sound and n is the frequency emitted by the source, then the difference between appearent frequencies heard by the observer is

A

` (2nv_0)/( v) `

B

` (nv_0)/( v) `

C

` (v)/( 2nv_0)`

D

` (V)/( nv_0)`
