Light travels slower through denser media, so it travels faster through water than through a diamond.
In a vacuum, light travels at a constat speed. It won't get faster or slower over time. In other substances (e.g., in water) light moves at a speed determined by the characteristics of the substance. Here, it won't get slower or faster with time, either.
it travels faster through air.
Light's apparent speed is fastest definitely in a vacuum and slower in water or glass. Light in air behaves more like in a vacuum than in water or glass.
It travels faster thru air
Slower in water.

Yes, light travels slower in water than in air.
As compared to what? Compared to air, or to a vacuum, light travels quite a bit slower in water.As compared to what?

yes they travel faster :)
Water is denser than air . Hence light travels faster in air than water.
Light travels much faster than sound, through wood.
Yoiu can explain that observation with the difference of the speed of light in air and in water. But in fact, the speed is FASTER in air and SLOWER in water.
slower
Since air has a lower optical density than water, light waves can travel faster in air.
Salt water is slower.
