Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

Defines the refraction of light and provides an applet for investigating it.

Manipulate variables and measure angles as light is refracted in this interactive simulation.

An investigation into the total internal reflection of light, using a laser pointer. Accompanied by an explanation of what's happening, a discussion of Snell's Law, and links to additional information.

Children can look around corners with this homemade periscope. Great instructions at this Exploratorium site on how to build a periscope.
