Brewster angle and refractive index

For a glass medium (n 2 ≈ 1.5) in air (n 1 ≈ 1), Brewster's angle for visible light is approximately 56°, while for an air-water interface (n 2 ≈ 1.33), it is approximately 53°. Since the refractive index for a given medium changes depending on the wavelength of light, Brewster's angle will also … See more Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is … See more While at the Brewster angle there is no reflection of the p polarization, at yet greater angles the reflection coefficient of the p polarization is always less than that of the s polarization, almost up to 90° incidence where the reflectivity of each rises towards unity. … See more • Brewster angle microscope • Critical angle, the angle of total internal reflection.
