A commuter train passes a passenger platform at a constantspeed of 45.0 m/s. The train horn issounded at its characteristic frequency of 320 Hz.

(a) What overall change in frequency isdetected by a person on the platform as the train moves fromapproaching to receding?

(b) What wavelength is detected by a person on the platform as thetrain approaches?
