A ray of light in glass strikes a water-glass interface at an angle of incidence equal to one-half the critical angle for that interface. The index of refraction for water is $1.33$, and for the glass it is $1.43 .$ What angle does the refracted ray in the water make with the normal?
A) $47 ^ { \circ }$
B) $37 ^ { \circ }$
C) $32 ^ { \circ }$
D) $27 ^ { \circ }$
E) $42 ^ { \circ }$
