There are different types of glass so there is not a single answer. The speed of sound is approx 4,000 metres per second ( range 3500 - 4500 ms^-1).

What is the speed of light in a glass fiber optic cable with a refractive index of 1.52?
In any medium whose refractive index is 1.52, the speed of light is c/1.52 = 0.658 c =197,231,880 meters per second (rounded)
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.
Why does glass have different refractive index for light beams of different colours according to wikipedia?
It is not just glass, it is true for all media though which light can travel. If water [raindrops] did not, then you would never have a rainbow! The refractive index of a medium is a measure of the average refraction - as measured for white light. In fact, the angle of refraction depends on the wavelength of the light.If the two interfaces between the two media (air to glass and glass to air, for example) are parallel then the different refraction at the first interface is exactly offset what happens at the second interface. So a beam of white light gets split up into the spectrum at the first and recombines into a beam of white light at the second interface. However, if the two interfaces are not parallel - as in a prism, or a raindrop, the result will be white light being split into the spectral components.
What causes dispersion of light?
White light is made up of 7 colours. When put through a prism like a raindrop or a glass block, the 7 colours all travel at different speeds, because some slow down more than others. Thus, light is dispersed into it's spectrum
What are some examples of osmosis?
1.Wrinkling skin in water 2. plants moving water to stem 3.a substance moving through a barrier
How fast can sound travel through glass?
5000 meters per second
How fast does sound travel through brick?
Sound travels through brick at the speed of 3650 meters per second. Sound is a mechanical wave that can travel through many different types of media, such as water, cork, gold, and glass.
How many meters will a photon of light energy travel in one nanosecond?
About 0.3 meters in a vacuum. Divide that by 1.0003 to get the distance in meters per nanosecond through air. Divide by 1.5 for glass.
Does sound travel aster in steel or glass?
The speed of sound through glass is 3962 metres per second, which is about 13000 feet per second. In normal air, sound travels at a speed of 343 meters per second and in water the speed is 1,433 metres per second. Sound travels at a speed of 5,000m per second or 11,160miles per hour through steel. The speed of sound is dependant upon the medium through which it is travelling and not on the loudness or pitch. For instance, sound travels much better through water than through air.
How fast dose the speed of light travel?
The speed of light travelling in a vacuum is said to be exactly 299,792,458 meters per second. Remember this is in a vacuum, for if the light were to pass through some transparent material, such as glass or water it would marginally slow down.
What speed does light travel as it moves through glass with an index of refraction n equals 4.5?
It will travel with speed about 0.844 meter per second
Can both light and sound travel through glass?
Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.
Will sound travel faster through water or a glass window?
window, because sound travels fastest through solids, liquids second, and gases last.
When a ray if light enters a glass block does it slow down or speed up?
Yes it does change.When it moves through air it moves with 299 792 458 meters per second! when it moves through glass it moves with about 150 000 000 meters per second.It slows it.
A material that light can travel through is?
Glass
What is a material through which light waves can travel?
Light can travel through transparent and translucent glass.
Does light have a medium to travel through?
No, apart from "spacetime". But it CAN travel through a medium such as air or glass.
