The Doppler Pendulum Experiment
Lee, C. K.; Wong, H. K.
Physics Education, v46 n4 p440-442 Jul 2011
An experiment to verify the Doppler effect of sound waves is described. An ultrasonic source is mounted at the end of a simple pendulum. As the pendulum swings, the rapid change of frequency can be recorded by a stationary receiver using a simple frequency-to-voltage converter. The experimental results are in close agreement with the Doppler formula. (Contains 3 figures.)
