Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
Does light get faster when it moves?
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.
Does light travel faster in diamond or water?
Light travels slower through denser media, so it travels faster through water than through a diamond.
Why does a glass filled with water distort things?
because light travels slower through water
Light traveling through the air moves in a straight line an object viewed through water looks different because the light rays that travel through water are what?

Is speed of light uniform or not?
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
Does light travel slower threw water?
Yes, light travels slower in water than in air.
Does light travel more faster or slower as they enter water?
Slower in water.
Light traveling through the air moves in a straight line an object viewed through water looks different because the light rays that travel through water are what?

Is the speed of sound in cork greater than speed of sound in water?
No. The denser the material, the faster sound moves through it.
What does the phrase the speed of light mee?
It means the speed at which light moves. While it may seem that light advances instantaneously, in fact it does not - it moves at a speed of 300,000 kilometers per second. That's the speed in a vacuum; in other substances, it moves slower. For example, in glass or water it moves at about 2/3 of the speed it has in a vacuum.
What do light waves propagate through?
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
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.
