A ray in glass arrives at the glass-water interface at an angle of 48° with the normal. The refracted ray, in water, makes a 72° angle with the normal. The index of refraction of water is 1.33. The angle of incidence of a second ray in the glass is 37°. The angle of refraction of the second ray in the water is closest to:
Answer
a. 46°
b. 52°
c. 50°
d. 54°
e. 48°
