Acommuter train passes a passenger platform at a constant speed of 40.4 m/s. the train horn is sounded at its characteristic frequency of 350 hz. (a) what overall change in frequency is detected by a person on the platform as the train moves from approaching to receding? (indicate whether the frequency increases of decreases with the sign of your answer.) the response you submitted has the wrong sign. hz (b) what wavelength is detected by a person on the platform as the train approaches? your response differs significantly from the correct answer. rework your solution from the beginning and check each step carefully. m
