Kids learn about the behavior of light as a wave in the science of physics including reflection, refraction, and diffraction.

This site has several lessons all about sound. It introduces sound, then covers major principles of waves and the wave equation. Each lesson has interactive activities to keep you interested, and there are even some test questions.

Kids learn about the behavior of waves in the science of physics including reflection, refraction, diffraction, polarization, absorption, and interference.

What's in a wolf's howl -- a calling card, a warning, or an invitation? Hear the call of the wild, find out how wolves are making a comeback, and discover the ancient connection between dogs and wolves in this feature exhibit.

If you have a browser that supports Java, you may find this site interesting. A series of Applets allow you to investigate wave generation and behavior.

Understand how trigonometric functions can model periodic behavior. See the application of periodic behavior, amplitude, frequency in sound waves. Make sure to turn up your sound to load an audio file to play the given tone of the...
