A commuter train blows its horn as it passes a passenger platform at a constant speed of 60.0 m/s. The train horn sounds at a frequency of 325 Hz when the train is at rest. I have a) and b) i need c)
(a) What is the frequency observed by a person on the platform as the train approaches?
(b) What is the frequency observed by a person on the platform as the train recedes from him?
(c) What wavelength does the observer find in each case? Your response differs from the correct answer by more than 100%. m Your response differs from the correct answer by more than 100%. m
