A passenger is sitting in a train which is moving fast. The engine of the train blows a whistle of frequency 'n'. If the apparent frequency of sound heard by the passenger is 'f' then

(A)f = nCorrect
(B)f > n
(C)f < n
(D)f n

Answer: (A)

Solution

The Doppler effect arises from the relative motion between source and observer. Here the whistle (on the engine) and the passenger (in the train) move together with the same velocity, so there is no relative motion between them and the distance between them does not change. (In still air) the number
