The Doppler shift was first tested in 1845 by the French scientist B. Ballot. He had a trumpet player sound a 422 Hz note while riding on a flat-car pulled by a locomotive. At the same time, a stationary trumpeter played the same note. Ballot heard 3 beats/s. How fast was the train moving toward him? The speed of sound in air is 343 m/s. Answer in units of m/s.

A sound wave of frequency f=300Hz produced by a moving source 40m/s is observed by a stationary observer. The speed of sound in ambient air is 345 m/s. As the source moves toward the observer, how far does the source travel between subsequent wave pulses? What is the apparent wavelength of the sound wave as perceived by the observer? What is the frequency of sound perceived by the observer? Note, when the source is in motion, the speed of the...
