What happens to a ray of light that slows down when it hits a new medium at an angle?

A. It dims.

B. It brightens.

C. It bends.

D. It is absorbed.

The ray of light is going to bend when it enters a new medium. Example: When light travels from the air and hits a glass of water, the light will bend.

Answer: C. It bends.

Explanation:

When the ray of light passes from one transparent medium to another transparent medium, then the change in the direction of light rays occurs which is known as refraction.

Therefore, we can say that when a ray of light that slows down when it hits a new medium at an angle, then it bends (change in direction) either towards or away the normal ray depends upon the density of the medium from which it travels.
