Snell's Law: A light ray in glass arrives at the glass-water interface at an angle of ? = 48° with the normal. The refracted ray in water makes an angle ? = 61° with the normal, as shown in the figure. The index of refraction of water is 1.33. The angle of incidence is now changed to ? = 25°. What is the new angle of refraction ? in the water?
A. 30°
B. 56°
C. 54°
D. 60°
E. 62°
