Through an illustrated tutorial and some interactive practice problems, students learn about the law of reflection of light.

This physics department site provides a definition and explanation of the phenomenon of total internal reflection. Includes a diagram and an equation for calculating the critical angle for light approaching a surface.

[Free Registration/Login may be required to access all resource tools.] Students learn about total internal reflection. More specifically, they will learn what the critical angle is, how it is derived and how to solve for it in real life...
