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°
