A Light Ray in Glass Arrives at the Glass-Water Interface $\theta = 48 ^ { \circ }$

A light ray in glass arrives at the glass-water interface an an angle of $\theta = 48 ^ { \circ }$ with the normal. The refracted ray in water makes an angle $\phi = 72 ^ { \circ }$ angle 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 $\theta = 37 ^ { \circ }$ . What is the new angle of refraction $\phi$ in the water?

A) $46 ^ { \circ }$
B) $52 ^ { \circ }$
C) $48 ^ { \circ }$
D) $54 ^ { \circ }$
E) $50 ^ { \circ }$
