Take the time and energy learn about Earth's energy budget. An engaging unit of four lessons focuses on the components that make up Earth's energy budget. Future scientists come up with a formula for the energy budget, then use software...

Students define and discus the concepts of wave fronts and rays. In groups, they distinguish between specular and diffuse reflections and use Snell's Law to predict the path of light rays. They calculate the speed of light through...

[Free Registration/Login may be required to access all resource tools.] In this module, discover and solve problems involving the index of refraction, and investigate problems involving Snell's Law.

Informational site provides illustrated tutorial of light reflection. Also discusses the law of reflection.

A video and a short quiz on the properties of light.

An in-depth discussion on reflection of light can be found here. Among the topics discussed include are the difference between specular and diffuse reflection, concave and convex mirrors, facets, total internal reflection, and much more....
