Question

For which angle of incidence reflection ray is completely polarized

Answer 1

Polarization by reflection. When light travels from one medium to another medium, if the angle of incidence is equal to polarizing angle or Brewster angle reflected rays from the boundary will be plane polarized. For this angle of incidence reflected ray and refracted ray will be mutually perpendicular to each other.
