This Flash animation provides a simulation of the Doppler effect. The user can change the speed of the wave source and can move a microphone to detect the wave frequency at different points relative to the moving source. The resulting wave pattern can be both observed and heard. Instructional notes outlining the details of the Doppler effect are provided.
This material is part of a web site for a second semester physics course for majors covering gravity, fluids, waves, and thermodynamics.
