What happens to light when it passed from air to water?

Correct Answer: it speeds up
it contracts
it brightens
it bends

Explanation: Refraction is another way that waves interact with matter. Refraction occurs when waves bend as they enter a new medium at an angle. You can see an example of refraction in the Figure below . Light bends when it passes from air to water or from water to air. The bending of the light traveling from the fish to the man’s eyes causes the fish to appear to be in a different place from where it actually is.
