It speeds up.

Its speed does not change.

Answer 1

(assuming from air) As light enters water it gets refracted and since air is less dense than water, it slows down. 

Denser = slow down, less dense = speed up

Answer 2

What happens when light enters water is that: B. It slows down.

Light refers to as an electromagnetic wave which causes a disturbance in a medium while progressively transporting energy from its source to another location, without the transportation of matter.

Typically, light wave travels through an empty space (vacuum) because it doesn't require a medium of propagation.

However, there are two (2) main mediums that slows down the speed of light waves and these are:

I. Water.

II. Window glass.

In conclusion, the speed of light slows down (reduced) as it enters water because water is a denser medium.
