This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Home page for a hypertext physics course on auditorium acoustics and acoustical design.

Explains single slit diffraction and models how to calculate different characteristics of the light waves.

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...

Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

This page and the many pages which are indexed to focus on the behaviors of sound which characterize it as a wave. Reflection, refraction, interference, diffraction and more are clearly illustrated and explained.

A tutorial from a hypertext physics course book that discusses reverberation. Illustrated.

A discussion of refraction and its application to sound waves. Using analogies, graphics and real-life applications, this page and those that accompany it explain why and when sound waves bend.
