University of Colorado: Ph Et Interactive Simulations: Bending Light
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.
Exploratorium
Exploratorium: Critical Angle
Students can see light reflected and refracted in this demonstration. They will also discover the total internal reflection of light.
