Chinese-language Java applet illustrating Fermat's principle that light follows the fastest path between any two points. Excellent animation and accompanying text. Relates Fermat's principle to Snell's law.

An interactive Java applet game in which the reflection of light is compared to the path of a billiard ball. Users view images of a target ball and try to direct a cue ball in such a manner as to hit it.

A Java applet which allows the user to emulate a refracting telescope and a light microscope. This is a great site to get information on the subject and better understand it through diagrams and charts.
