A source of sound S is moving with a velocity 50 m//s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of sound in the medium is 350 m//s .

Derive an expression for apparent frequency when the source is moving and listener is stationery

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
