Acommuter train passes a passenger platform at a constant speed of 43.1 m/s. The train horn is sounded at its characteristic frequency of 322 Hz. (a) 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 of decreases with the sign of your answer.) (b) What wavelength is detected by a person on the platform as the train approaches?

1) A pedestrian waiting for the light to change at an intersection hears a car approaching with its horn blaring. The car's horn produces sound with a frequency of 381 Hz, but the pedestrian hears a frequency of 389 Hz. How fast is the car moving? 2) A train moving with a speed of 31.3 m/s sounds a 151 Hz horn. What frequency is heard by an observer standing near the tracks as the train approaches?

A commuter train blows its horn as it passes a passenger platform at a constant speed of 37.3 m/s. The train horn sounds at a frequency of 340 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.
