- Index of Refraction
Refraction is defined as the change in direction of a wave of light as it passes from one medium to another. The amount that the light changes direction depends on the indices of refraction of each medium, and is described quantitatively by Snell's law (Equation 1). The index of refraction of a … - Chromatic Dispersion
Chromatic dispersion, also referred to as chromatic aberration, is a phenomenon where the speed and direction of light propagation in an optical medium depends on the wavelength of light. The interaction of the particular wavelength of light with electrons in the medium gives rise to this ph…
