When a light beam reaches the boundary of two different media, usually a part of it is reflected and a part of it is refracted. Determine the incident angle provided that the reflected and refracted rays are perpendicular. This special angle is called Brewster’s angle. Express your result in terms of the two refractive indices n1 and n2 .
