Best Answer

The speed of light is greatest in vacuum, and somewhat less in any material medium.

The exact number depends on the individual material. They're all different.

How does the average speed of light glass compare with its speed in a vacuum?

About 2/3 its speed in a vacuum.


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.


Does the speed of light minimum in air or water or glass or vacuum?

How does light change speed from glass to air?

In glass, light will go somewhat slower than in a vacuum. Air is almost like a vacuum, with respect to the speed of light - some difference still exists, though.In glass, light will go somewhat slower than in a vacuum.

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 .

How does the speed of light in glass compare to the speed of light in a vacuum?

It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.


What happens to frequency does the speed of light ever change?

The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.

How does the speed of visible light compare with the speed of gamma rays when both speeds are measured in a vacuum?

The speed of light in glass is the reciprocal of the refractive index of the glass or 1/(refractive index). Not all glass is the same: its refractive index can range from less than 1.5 for Pyrex (a borosilicate glass) to more than 1.9 for (impure) flint glass. This means the speed of light in glass can range between 0.52 and 0.68 of its speed in vacuum.


What happens when light passes through something?

The velocity of light is greatest when travelling through a vacuum. When travelling through something else, a glass material say, then its velocity is slower. The refractive index is the ratio of the speed of light in a vacuum to the speed of light in that substance. For example light travels in a vacuum about 1.3 times as fast as in water, so we say water has a refractive index of 1.3. And it is likely that the velocity in the glass will be different at different wavelengths of light.
