When a ray of light strikes a nonmetallic surface, some of the light is reflected and some is refracted. Brewster’s angle is the angle of incidence for which the reflected and refracted beams are 90° apart. The significance of this angle is that it leads to a reflected ray which is completely polarized. (a) Sketch the incident, reflected, and refracted rays for a situation involving Brewster’s angle. (b) Compute Brewster’s angle for water. (Hint: the index of refraction of water is 1.33 and you might find the trigonometric identity sin(90° − θ ) = cosθ to be useful.)
