Use the relation:

speed in a medium = speed of light in a vacuum / refractive index

i.e. v=c/n

Hence

v = 300000000/1.333 = 225060000 m/s

The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?

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".


How do you calculate refractive index of a given solvent?

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.


The speed of light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?

Also 1.5. That's how the index of refraction is defined.


If the speed of a light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?

1.5 no units (APEX)


What of a material indicates how much the speed of light in the materials changes as light passes through?

The property of a material that indicates how much the speed of light changes as it passes through is called the material's refractive index. This index is a measure of how much the speed of light is reduced in a material compared to its speed in a vacuum. The higher the refractive index, the more the speed of light is reduced in that material.


What is the speed of light in carbon disulphide if its refractive index is 1.628?

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.


Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?

Refractive Index= Speed of Light in Vaccum / Speed of Light in the material


What is the index of refraction?

The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.


What equation is used to determine speed of light through material?

The equation used to determine the speed of light in a given material is v = c / n, where v is the speed of light in the material, c is the speed of light in a vacuum, and n is the refractive index of the material.


What is relative refractive index?

The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.


What is the property of a material that indicates how much it reduces the speed of light?

I think the property referred to on the question is the refractive index. Refractive index (n) is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in the given material (v).n = c/vSo for glass, with a refractive index of 1.5, the speed of light in the material would be 200,000,000 m/s compared to speed of light in a vacuum of 300,000,000 m/s.
