The Physics Classroom: Light Waves/color: Two Point Source Interference Pattern
Students investigate the underlying causes of two-point source interference pattern. They also discover that the spatial separation between the antinodal and nodal lines in the pattern is related to the wavelength of the waves.

Ucar: Blue Skies and Red Sunsets
Find out how some wavelengths of light are scattered more than others producing blue skies and red sunsets.
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...
