Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

In this frequency activity, students use the speed of sound to determine the frequency in which sounds are heard in 5 different word problems.

This hypertext physics course page illustrates and explains the Doppler effect. Users perform practice calculations for frequency shifts using the Doppler equation.
