Refraction of Water Waves Images

The model below shows a light wave in a fish tank. The solid arrow represents the wave moving through saltwater, which has a density of 1.03 g/cubic cm. The glass of the tank has a density of 2.6 g/cubic cm.

Which dashed arrow represents the path the light wave will travel after reaching the glass?

• A

• B

• C

• D
