The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.

Explains what diffraction and interference are, and what kinds of patterns are produced when light waves pass through a single slit, a double slit, or a diffraction grating. Includes three problems for students to try, with solutions...

Most of us have seen the rainbow-hued breakdown of the composition of light. Light is of course a form of energy. A magnetic field changes the behavior of light- a phenomenon known as the Zeeman effect.
