Light Dispersion through a Glass Slab
This applet shows a glass slab and two beams of light. The beam on the left of the slab is white and the beam on the right is the broken up version of the first beam into the seven colors of the rainbow. Rock the slab, by clicking on it, and see the effect which various angles of incident light have on the dispersion.
