A light ray in glass arrives at the glass-water interface an an angle of 0 = 48° with the normal. The refracted ray in water makes an angle = 72° angle with the normal, as shown in the figure. water glass The index of refraction of water is 1.33. The angle of incidence is now changed to 0 = 37°. What is the new angle of refraction w in the water? Select one: 50° 52° 46° 54° 48° The correct answer is: 48°
