Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

This laboratory exercise is designed to introduce students to salts and their unique color given off while burned. Students will obtain several salt solutions to observe the color of flame when burned.

Physiclips thoroughly presents mechanics concepts about light with animations and film clips. Learn about light and color, wavelengths, speed of light, electromagnetic waves, Young's experiment, and photons.

[Free Registration/Login may be required to access all resource tools.] Overview of the different colors in visible light and how they relate to its wavelength, how a prism separates visible light into its different colors, the colors of...

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

A thorough, multipage discussion of color and color television sets that explains how an image is formed on the television using red, green, and blue light. Understandable discussion, excellent graphics, and many interactive Java applets.

An online exploration where students learn the basics about light and the properties of waves and the electromagnetic spectrum. Students will also learn how to measure wavelength and frequency so they can understand the electromagnetic...

The phenomenon of light dispersion is explained with a formula and a practice form for calculating Abbe's number.

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.
