When electromagnetic radiation falls on a surface, then the angle between reflected light and refracted light is 90° at an angle, called?

Critical angle

At any angle both rays are perpendicular

Brewster’s angle

Inclination angle

Explanation

Brewster’s angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a surface with no reflection.

At this angle, the reflected and refracted rays are perpendicular (90° apart).
