The observer is moving with velocity v0 towards the stationary source of sound and then after crossing moves away from the source with velocity v0 . 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 apparent frequencies heard by the observer is
