Light Dispersion through a Glass Prizm

Rock the prizm using the mouse.

This applet displays a prizm and two light beams (one going into the prizm and the other going out). The beam on the left is white, and the beam on the right is the white beam broken into the seven rainbow colors. You can rock the prizm by clicking on it, notice the effect that various angles of incident light have on the dispersion angles.
