Polarization by reflection of light
PolarizationPolarization is the action of restricting the vibrations of a transverse wave, especially light, wholly or partially to one direction.Polarization by the reflection of light:Brewster's ...
Polarization, however, is an important property of light that affects even those optical systems that do not explicitly measure it. The polarization of light affects the focus of laser beams, influences the cut-off wavelengths of filters, and can be important to prevent unwanted back reflections.
