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

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)
If the speed of light in a vacuum is 1.2 times that of the speed of light in a given material what is the index of refraction for that material?
2 (no units)
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
How do you calculate speed of light wave with refractive index?
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.
How is the index of refraction of s medium related to the speed of light inThe medium?
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
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".
What do you mean by refractive index and what are factor in which it depends?
Refractive index is defined as the ratio of the speed of light in vacuum to the speed of light in given media.
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)
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 speed of light in more refractive index?
Higher the refractive index, less the speed of light
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 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.
