WebAngle θ 2 is determined from θ 1, using Snell's law of refraction. Angle θ 2 = θ 2 by geometry, θ 3 = θ 4 by law of reflection, and θ 4 = θ 5 by geometry. θ 6 is related to θ 5 by Snell's law of refraction, in the same ration as θ 1 to θ 2. Therefore, θ 6 —the angle of the ray leaving the water—must be 30 degrees. http://light.ece.illinois.edu/ECE460/PDF/Chap_09_%20IX-%20Geometrical%20Optics.pdf
