The discussion centers on Brewster's angle and its effect on refracted light. When light hits a medium at Brewster's angle, if the incident light is polarized parallel to the surface, it is entirely reflected with no refraction. Conversely, if the light is polarized at an angle other than parallel, the non-parallel component is refracted. For randomly polarized light incident at Brewster's angle, the refracted light exhibits partial polarization, with 100% of parallel polarized light transmitted and approximately 85% of perpendicular polarized light transmitted, resulting in a predominantly parallel polarization in the refracted ray.
