A ray of sunlight traveling through water (n=1.32 - 1.34 across the visible spectrum) has an
incident angle of 80° when it encounters a transparent aquarium wall with index of refraction
n=1.2. There is air with index n=1 on the other side of the wall and the wall surfaces are
parallel. Which statement below is true?
Select one:
a. Light emerges on the other side of the wall traveling parallel to the incident ray.
b. Light emerges on the other side of the wall but different colors now travel in different directions.

In Figure, light is incident at angle 0,=40.1° on a boundary between two
transparent materials. Some of the light travels down through the next
