I think the word you're looking for is "refraction."
Vecause light travels slower throughwater.:)

i.e. mechanical waves travelling through water? Light of course. Otherwise how would you see the ripples? Light travels at 299,792.458 km/s.
Light travels slower through a medium. Generaly the dencer the medium the slower light travels. Light travels fastest through a vacuum assuming its speed is not being affected by gravity which also affects the speed of light. Examples. A very very thick piece of glass will appear thinner than it actually is and a streight stick will appear to bend if put into water at an angle.
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
Light travels faster.
Light travels faster.

Sound travels faster in water.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
In water
water is a medium through which light travels. water does abosrb a verysmall amount of light though
They disperse.
No.
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.
Light travels slower through denser media, so it travels faster through water than through a diamond.
Yes, light travels slower in water than in air.
