Brewster's angle
Videos
Brewster's angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light i
Photographs taken of a window with a camera polarizer filter rotated to two different angles. In the picture at left, the polarizer is aligned to pass only the vertical polarization which is strongly reflected from the window. In the picture at right, the polarizer has been rotated 90° to eliminate the heavily polarized reflected sunlight, passing only the p (horizontal in this case) polarization.
Fresnel equations

The Fresnel equations describe the reflection and transmission of light when incident on an interface between different optical media. They were deduced by French engineer and physicist Augustin-Jean
Brewster's angle
…with different refractive indices, some of it is usually reflected as shown in the figure above. The fraction that is reflected is described by the Fresnel equations, and depends on the incoming light's polarization and angle of incidence. The Fresnel equations predict that light with the p polarization (electric…
