Why light travels slower in water than in air?
Light travels slower in water than in air because when light enters the water medium, according to the collision theory, the particles of the water gets some of the light energy and displaces light from its real path. As the energy is absorbed, it is a fact that on decreasing the energy of anything, it will get much slower in performing that work. So light travels slower in water than in air.
Why light enters water does it speed up or slow down?
Slows IF it enters the water from air (and not - say - glass).
As energy moves in waves through the water the water moves?
in small circular movement
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).
What moves forward in a water wave?
Energy moves forward in a wave.

What happens when light travels to air to water?
The speed of the light wave slows Some light is reflected off the surface of the water The light that enters the water is "refracted" (the direction of propagation changes due to the different indexes of refraction in air and water) Eventually the water will absorb all the energy of the light if the water is deep enough
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.
Why light enters water does it speed up or slow down?
Slows IF it enters the water from air (and not - say - glass).
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.

in small circular movement
As energy moves in the waves through the water the water moves?

When light moves from air to water the light will?
Refract
Most water enters and leaves cells by?
Water moves between cells by osmosis, down a concentration gradient.
What moves forward in a water wave?
Energy moves forward in a wave.
What energy transformations take place during photosynthesis?
Plants give off oxygen and glucose, the light energy from the sun enters through the chloroplasts, plants also need carbon dioxide(CO2) and water(H2O) to make glucose and oxygen.
