Because it slows down when entering water.

How does the speed of light change when it enters the water?
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.

How do the light waves coming from the pencil change speeds?
when the pencil enters the water
Where do the light waves change speed from a pencil?
ACTUALLY ! Its when the pencil enters the water .
What happens when light passes into water?
The light will change directions (to be closer to the normal) once it hits the water. This is known as refraction which is a property of light. In this case, you have 2 media (plural form of medium). The two are air and water. The reason it changes direction is because air allows a different speed of light than water. Water is denser which is why light can't travel as fast. This change in the speed of light is what causes the light to change direction once it hits the water. In conclusion, after light hits the water, it will change directions (to be closer to the normal) due to the fact that the medium is changed(from air to water) which results in a change in the speed of light.

How does water change the appearance of substances?
Well as far as i know, when light enters water, it is refracted (bent), this makes the object that the light hits appear to look different as it wold in the air.
How does the direction of a ray of light change as it passes from air into water?
When a ray of light travels it is in a wave and when it enters from air to water it becomes more dense and harder to move so the waves are refracted.
Why light enters water does it speed up or slow down?
Slows IF it enters the water from air (and not - say - glass).
Why a regular object bends in water?
Water's particles are denser than air's, so when the light enters water, the light rays slow down, so travel at a shallower angle to the angle at which the light enters (incidence).
When light passes from water to air the light rays are what?
If you are referring to a situation in which light is reflected from water back into the air, then the light rays are "polarized." All light rays travel in straight lines, but polarized light is light that enters a medium from many directions, but are exited (reflected or refracted or merely cut out, like in sunglasses) in one direction.
