Description
Light in which all vibrations are parallel to one plane. Natural light, sunlight and artificial light , is incoherent meaning it contains wave vibrations from all different directions. Polarized light is a single orthogonal component whose vibration vector travels in one direction. Light can be separated, or plane polarized, using reflection, refraction, or dichroic characteristics of a mirror, crystal, or filter. Materials which have two different path lengths depending on the direction of the polarized light are said to be birerefringent.
