The observer is moving with velocity 'v0...

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 spurce then the difference between apparent frequencies heard by the observer is

A

` (2nv_0)/( v) `

B

` (nv_0)/( v) `

C

` (v)/( 2nv_0)`

D

` (V)/( nv_0)`
