Doppler Effect

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

Show answer and solution

The passenger and the engine move together, so there is no relative motion between source and listener.
No Doppler shift: $f = n$ .
So the answer is (a) $f = n$ .
