Key Concepts

Dispersion and Wavelength Dependence

Dispersion describes how a material's refractive index varies with the wavelength of light. Although Brewster’s angle is computed using the refractive index, which can change slightly with wavelength, in many cases the effect is minimal. This means that for many practical purposes, the angle at which light is completely polarized does not significantly depend on the wavelength of the light.

Brewster's Angle

Brewster's angle is the specific angle of incidence at which light reflected from a surface becomes completely polarized, meaning the reflected light has its electric field oscillating in only one direction. It is defined by the condition that the reflected and refracted rays are perpendicular to each other, leading to the relation tan(?_B) = n?/n?, where n? and n? are the refractive indices of the two media involved.

Polarization of Light

Polarization refers to the orientation of the oscillations of the electric field vector in a light wave. In the context of reflection, when light strikes a surface at the Brewster angle, the reflected light emerges with its polarization aligned parallel to the interface, resulting in the elimination of the component perpendicular to the plane of incidence.
