A source of sound emitting a tone of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is

Question

(d) As source and observer both are moving in the same direction with the same velocity, their relative velocity is zero. Therefore,$n^{'} = n = 200\ Hz$
