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, we need to find the real frequency of the whistle of train A (f1) given that the real frequency of the whistle of train B (f2) is 600 Hz, and the observer hears no beats. This indicates that the perceived frequencies of both trains are equal when they reach the observer. ### Step-by-Step Solution: 1. **Identify the Given Values:** - Velocity of sound (v) = 330 m/s - Velocity of train A (vA) = 15 m/s - Velocity of train B (vB) = 30 m/s ...
