Overall change in frequency is detected-person on platform

Reference no: EM13666026

A commuter train passes a passenger platform at a constant speed of 44.0 m/s. The train horn is sounded at its characteristic frequency of 320 Hz.

a) What overall change in frequency is detected with a person on the platform as the train moves from approaching to receding?

b) What wavelength is detected with a person on the platform as the train approaches?
