Students learn the basic properties of light--the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic...

A series of thought-provoking multiple-choice questions from the University of Maryland on the topic of sound and acoustics. One question pertains to the acoustics of a furnished room with two speakers; demands a basic understanding of...

In this experiment, students go outside and create a simulation of P and S waves traveling across a 30-meter span. This is repeated using a 30-meter square. They experiment with P and S wave behavior, record results, and use...

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.

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.

The discovery of radio waves, which was widely seen as confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology, was made by German physicist Heinrich Hertz. In the...

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.

Describes the physics behind animals' ability to dry themselves by shaking to remove water.

For this activity, students use an oscilloscope to explore the behavior of sound waves.

What colors do you see in a bubble? Why do you see colors in a bubble? Use this site to find out the answer to these questions with this easy experiment.

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...
