The Physics Classroom: Light Waves/color: Electromagnetic and Visible Spectra
This illustrated physics tutorial explains the electromagnetic and visible spectra of light using illustrated examples and interactive practice problems.
NASA
Nasa: Tour of the Electromagnetic Spectrum: Visible Light
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

Ucar: Blue Skies and Red Sunsets
Find out how some wavelengths of light are scattered more than others producing blue skies and red sunsets.
TeachEngineering
Teach Engineering: Graphing the Rainbow
Students are introduced to different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn...
