Polarization by reflection One way to polarize light is by reflection. If a beam of light strikes an interface so that there is a 90° angle between the reflected and refracted beams, the reflected beam will be linearly polarized. The direction of polarization (the way the electric field vectors point)is parallel to the plane of the interface. The special angle of incidence that satisfies this condition, where the reflected and

Unformatted text preview: refracted beams are perpendicular to each other, is known as the Brewster angle. The Brewster angle, the angle of incidence required to produce a linearly-polarized reflected beam, is given by: This expression can be derived using Snell's law, and the law of reflection. The diagram below shows some of the geometry involved. Using Snell's law:...
