A ray of light exits a diamond (index of refraction 2.42) and enters one of three transparent liquids—water (1.33), glycerol (1.50), or xylol (1.70). The incident angle inside the diamond is the same for all three cases. Which of the following correctly ranks the refracted angles in the liquids from largest to smallest?
a) xylol > glycerol > water
b) glycerol > water > xylol
c) water > glycerol > xylol
d) water > xylol > glycerol
