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 .
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.
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 average speed of light in glass compare with its speed in vacuum?
Depends on the refractive index of the medium itself

How does the speed of light compare in water glass and diamond?
The speed of light is slower in water and glass compared to its speed in a vacuum, but faster in diamond. This difference is due to the different optical properties of these materials, which affect how light propagates through them. In water and glass, light travels at about 3/4 of its speed in a vacuum, while in diamond, light travels even faster than in a vacuum.
Compare and contrast the speed in water and in the glass?
The speed of light in water is slower than in a vacuum. This is due to the higher refractive index of water compared to air, causing light to bend more in water. In a glass, the speed of light is also slower compared to a vacuum, though the exact speed will depend on the composition of the glass.
What distance does light travel in glass during the time that it travels 1.0 meters in vacuum?
Light travels at a slower speed in glass compared to vacuum. The ratio of the speed of light in vacuum to the speed of light in glass is called the refractive index of glass. So, the distance light travels in glass would be the distance it travels in vacuum divided by the refractive index of glass.
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 travels the fastest, with a speed of 299,792 kilometers per second in a vacuum. Sound travels at around 343 meters per second in air. Microwaves travel slower in glass compared to a vacuum, but their speed is still faster than sound. A rocket in space can travel at speeds up to several kilometers per second, depending on its propulsion system.
Suppose light travels 1.5 times faster in a vacuum than it does in glass. What is the index of refraction for glass Express your answer as a decimal.?
The index of refraction for glass is calculated by taking the speed of light in a vacuum and dividing it by the speed of light in glass. Since light travels 1.5 times faster in a vacuum, the index of refraction for glass would be 1 divided by 1.5, which equals 0.67.
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.?
