How does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
How does the average speed of light in glass compare with its speed in a vacuum?
3/4th
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.
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 .

Does the speed of light minimum in air or water or glass or vacuum?
glass
How does light change speed from glass to air?
Light changes speed when it moves from glass to air due to the difference in optical density between the two mediums. In glass, light travels slower due to the higher density, resulting in refraction as it enters the less dense air. This change in speed causes the light to bend and change direction.
What travels the fastest sound in air rocket in space light in vacuum microwaves in glass?
light in a vacuum
Does light travel faster in glass then it does in a vacuum?
No, slower.
Light travels faster in glass than it does in a vacuum.?
No
Does a light travels faster in glass than it does in a vacuum?
No
Does light travel fastest in space in air in water or through glass?
Light travels fastest in a vacuum, such as in space. It slows down when passing through different mediums like air, water, and glass due to interactions with atoms and molecules in those materials, which cause the light to refract and bend.
