A light ray in glass arrives at the glass-water interface at an angle of θ = 48° with the normal.The refracted ray in water makes an angle θ = 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 θ = 25°.What is the new angle of refraction φ in the water?
A)30°
B)56°
C)54°
D)60°
E)62°
