Calculate the wavelength for the receding train

Reference no: EM13553233

A commuter train blows its horn as it passes a passenger platform at a constant speed of 39.1 m/s. The train horn sounds at a frequency of 305 Hz when the train is at rest. What is the frequency observed by a person on the platform as the train approaches? What is the frequency observed by that person as the train recedes from him? Calculate the wavelength for the approaching train. Calculate the wavelength for the receding train.
