Find what overall change in frequency is detected

Reference no: EM13679469

A commuter train passes a passenger platform at a fix speed of 41.9 m/s. The train horn is sounded at its characteristic frequency of 320 Hertz.

(a) Find 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 or decreases with the sign of your answer.)
