The speed of light in air compares with the speed of light in glass because?

The speed of light in air is much faster than in glass. This is because the density of glass is much higher than that of air so it slows the lightwave down much more.

Where will be speed of light minimum-water or air or vacuum or glass?
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
How does the speed of light that emerges from a pane of glass compare with the speed of light incident on the glass?
Those speeds are equal, even though the speed of the light was temporarily less while it was inside the glass.
The colour of light which travels through glass with the minimum speed is?
Light does not change speed when it goes through glass.
How does a window reflect light?
A window reflects light because light, which is a wave, travels slower in glass than in air. It travels at about 2/3 the speed in glass as it does in air. Also light travels at about 3/4 the speed in water as it does in air and so that is the reason light reflects off the surface of water. The greater the difference in speed between the two mediums, the more light is reflected at the surface boundary. An amazing experiment is to submerge glass in a transparent liquid that has the same "index of refraction". The 'index of refraction" of a substance is simply the measure of the speed with which light travels in the substance. If you submerge the glass, and the speed of light is the same in the liquid as in the glass, the glass seems to disappear. The reason is seems to disappear is because light is no longer reflected off the surface of the glass, and if you think about it, that is the only reason that you can see a glass in the first place.
What happens to the speed of light when it passes from water to glass?
the speed of light it different when it is passed through air, water or glass because all these have different optical densities. Speed of light is fastest in air, slower in water and slowest in glass.
Why light is refracted as it moves from air into glass?
That's related to the fact that the speed of light in glass is slower than the speed of light in air.
Why does light bend when it goes through glass at an angle?
Change in speed of the light in glass. Fermat showed that time is invariant in light paths. This results in Light following the Law of Signs. sin(Air Angle)/speed in air = sin( Glass Angle)/speed in glass .
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
What will be the speed of light in glass?
fast
How does the speed of light compare in water glass and diamond?
Speed of light in vacuum = ' c '-- Speed of light in Air . . 99.97% of ' c '.-- in Water . . . . . . . . 75% of ' c '.-- in Crown Glass . . . 64.9%-- in Flint Glass . . . . . 61.7%-- in Diamond . . . . . . 41.3%
Why does the speed of light vary?
The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
How does the average speed of light in glass compass with its speed in a vacuum?
There are several different types of glass, and light has a somewhat different speed in each of them. On the average, the speed of light across all typical types of glass is in the neighborhood of 2/3 its speed in vacuum, or around 200,000 km/sec .
