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...

The interference of two sets of circular waves with the same frequency and the same amplitude results in a standing wave pattern. These standing wave patterns are known as two-point source interference patterns since they result from the...
