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 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
What is the average constant speed of light in vacuum?
The speed of light in vacuum is 299,792,458 meters per second, and that's not an average. That's what it always is.
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 compare with it's speed in a vacuum?
In vacuum, the speed of light is a constant c = 300 000 000 m/s. In a transparent medium, light slows down by a factor of 1/n where n is called the refractive index of the medium. The refractive index of most common glasses is around 1.5 (3/2), so light will travel at a speed v = c/n = (2/3)c = 200 000 000 m/s in the glass.
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?

How does the average speed of light in glass compare with its speed in vacuum?
Depends on the refractive index of the medium itself
Does the speed of light minimum in air or water or glass or vacuum?
glass
What travels the fastest sound in air rocket in space light in vacuum microwaves in glass?
light in a 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.

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'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.
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.
What do use to light a light bulb?
Glass and metal. More specifically, a filament, wires that conduct, and a vacuum inside a glass shell.
