Unformatted text preview: for E in the plane of incidence the electron-oscillators on the surface of the dielectric will vibrate under the influence of the refracted wave. However, shows the angle between the reflected wave and the dipole axis (the direction of oscillation) is now small and thus very little light will be reflected in this direction. Figure %: Polarization by reflection. If the angle with the dipole axis is made to be θ = 0 o , then the reflected wave vanishes. This angle is called Brewster's angle and is given by: tan θ p = For unpolarized light incident on the surface at Brewster's angle, the reflected light is polarized perpendicular to the incident plane, or parallel to the surface. At other angles, the reflected light will be partially polarized....
