Two trains A and B approach a station from opposite sides, sounding their whistles. A stationary observer on the platform hears no beats. If the velocities of A and B are 15 m/s and 30 m/s respectively and the real frequency of the whistle of B is 600 Hz, find the real frequency of the whistle of A. (Velocity of sound = 330 m/s)

To solve the problem step by step, we will use the Doppler effect formula for sound waves. ### Step 1: Understand the Problem We have two trains A and B approaching a stationary observer. The observer hears no beats, which means the apparent frequencies of both whistles are the same. ### Step 2: Define the Variables - Let \( f_A \) be the real frequency of the whistle of train A. - The real frequency of the whistle of train B, \( f_B = 600 \) Hz. ...
