Dispersion and Scattering

When a wavelength changes index of refraction, there is some scattering of the wavelengths and this phenomena is called dispersion.

The Main Idea

Different frequencies of light contain different phase velocities because of the material they pass through's properties. When the velocity differs, dispersion occurs. The most recognizable act of dispersion is seen in most transparent materials, when there is a decrease in index of refraction, which leads to an increase in wavelength.
