Question:
A sound source of frequency f0 moves with speed us relative to still air toward a receiver who is moving with speed ur relative to still air away from the source.
(a) Write an expression for the received frequency f’.
(b) Use the result that (1 - x)-1 ≈ 1 + x to show that if both us and ur are small compared to v, then the received frequency is approximately
where urel is the relative velocity of the source and receiver.
