If the angle of incidence and the angle of refraction are complementary angles, the angle of incidence is referred to as the Brewster angle theta Subscript Upper BθB. The Brewster angle is related to the indices of refraction of the two media, n 1n1 and n 2n2, by the equation n 1 sine theta Subscript Upper B Baseline equals n 2 cosine theta Subscript Upper Bn1sinθB=n2cosθB, where n 1n1 is the index of refraction of the incident medium and n 2n2 is the index of refraction of the refractive medium. Determine the Brewster angle for a light beam traveling through water (at 2828 degrees°C) that makes an angle of incidence with a smooth, flat slab of crown glass. The index of refraction for water is 1.261.26 and the index of refraction for crown glass is 1.531.53. theta Subscript Upper BθBequals=nothing degrees° (Type an integer or decimal rounded to the nearest tenth as needed.)
