Why light enters water does it speed up or slow down?
Slows IF it enters the water from air (and not - say - glass).
Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
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).
Does light speed up or slow down when it leaves water into the air?
The speed of light in air is almost but not quite the same as its speed in vacuum,whereas its speed in water is about 25% less.So when light passes from air into water, its speed drops by about 25% .
Does light increase or decrease through pure water?
The light would decrease. This is because light does not need a median to move throw. The water is a form of median. So it would slow the light down. Sound needs a median to move. This would bethe air for the sound.
What slows down the speed of light?
Light will slow down if it goes through just about anything that is not a vacuum, for example air, glass, water.

no. they slow down.
Does the speed of light ever slow down?
The speed of light is different in different substances ... air, water, glass, jello, etc.

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 enters water it slows down when it exits it speed up again How is this possible and where does it get the energy to do so?
The hydrogen in water causes the speed of light to slow down. When it exits, the air and gravity cause it to speed up again. It gets the energy from gravity.

On Earth which forces tend to slow an object down?
Air resistance, Gravity, Friction and Water resistance(Water and Air resistance depending if it's in air or water)

Does air slow down when it goes from water to air?
Yes. Air rises very quickly through water, but then disperses and quits rising when it pops free of the water and reaches the air.
How ligth is affected passing throug water?
When light passes from air to water, the light is refracted because water is denser than air and therefore slows down the speed of the light.
What happens when light passes air into water?
it slows down.
