The speed of light in any medium is
speed of light in vacuum/refractive index of that medium.
Refractive index is a measure of how much light bends as it passes from one medium to another. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. A higher refractive index indicates a slower speed of light and more bending.
The speed of light in a medium is given by the formula v = c/n, where c is the speed of light in vacuum and n is the refractive index of the medium. Thus, in carbon disulphide with a refractive index of 1.628, the speed of light would be approximately 184,266 km/s.
To find the wavelength of light in Plexiglass, you need to take into account the change in speed of light. Since light travels at 67% of its speed in air in Plexiglass, you would need to calculate the wavelength using the formula: wavelength in Plexiglass = wavelength in air / refractive index of Plexiglass. Refractive index of Plexiglass is calculated as speed of light in air / speed of light in Plexiglass.
The speed of light in a medium can be calculated by dividing the speed of light in a vacuum (299,792,458 meters per second) by the refractive index of the medium. Therefore, in a medium with a refractive index of 1.5, the speed of light would be approximately 199,861,639 meters per second.
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
Speed of light in water = speed of light in vacuum/refractive index of water
The refractive index of a solvent can be calculated by measuring the speed of light in that solvent and comparing it to the speed of light in a vacuum. It can also be determined using an Abbe refractometer, which measures the angle at which light bends when passing through the solvent. The formula for refractive index is n = c/v, where n is the refractive index, c is the speed of light in a vacuum, and v is the speed of light in the given solvent.
Refractive Index= Speed of Light in Vaccum / Speed of Light in the material
The absolute refractive index of a medium is a measure of how much light is slowed down when passing through that medium compared to the speed of light in a vacuum. It is a ratio of the speed of light in a vacuum to the speed of light in the medium. The absolute refractive index is a fundamental property of the material and is used to calculate how light rays will bend when entering or exiting the medium.
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.

I cannot answer this question without knowing the numbers for the glass
The speed of light in a material with a higher refractive index is slower compared to its speed in a vacuum. This is due to the interaction of light with the atoms and molecules in the material, causing it to bend or slow down as it propagates through the medium.
You can find the refractive index of a solution using a refractometer, which measures how light bends as it passes through the solution. The refractive index is calculated by comparing the speed of light in a vacuum to the speed of light in the solution. The refractometer provides a numerical value that corresponds to the refractive index of the solution.
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in mediumHence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.
speed of light is different for materials of different refractive index and also higher the refractive index lesser will be speed of light in that medium. so if light travels from rarer to denser medium (with respect to refractive index) then light waves will change their speed
