Step-by-Step Verified Solution

Since all the passengers in train A are moving with a velocity of 20 m/s therefore the distribution of sound intensity of the whistle by the passengers in the train A is uniform.

Trick : Total frequency =(1120−800)Hz=320 Hz

IIT-JEE 2007 Paper 2 Offline Physics - Waves Question 6 English Explanation

There is no relative motion between source and observer.

Therefore, all the passengers will hear the sound of same intensity.
