To solve the problem of finding the apparent frequency heard by a man traveling in a train towards a station where a whistle is blown, we will use the Doppler effect formula. Here are the steps to find the solution: ### Step 1: Identify the given values - Frequency of the whistle (f) = 200 Hz - Speed of the observer (train) (v_o) = 50 m/s (towards the source) - Speed of sound in air (v) = 350 m/s - Speed of the source (v_s) = 0 m/s (since the source is stationary) ...
