glass, and the critical angle for the glass-air interface. (/4) 3. The triangular face of a prism is an equilateral triangle. White light is directed at the side of the prism such that 0 = 50.0. The prism is made of crown glass. Its index of refraction ranges from 1.517 for the longest visible wavelengths to 1.538 for the shortest. Find the range of refraction angles for the light transmitted into air as the light leaves side BC. (/4) B AWaves T = 2mm hi d m = do T = 27Ng = 1 do + di n2 sin O T = 7 = Q n1 sin 62 G A n2 21 .
