Doppler Effect You are waiting at a train station when an approaching express train sounds its 400 Hz horn, warning everyone to stand back from the platform as it passes. If you perceive the frequency of the horn to be 425 Hz as the train approaches, how fast must the train be moving towards you? You may assume the speed of sound is 343 m/s.
