The index of refraction tells you by which factor the speed of light in the medium is slower than in a vacuum. This value is 1 for a vacuum, and a number greater than 1 for other media. The exact value depends on the medium.
Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.

"The refractive index is a measure of how much light bends or refracts when it is passed through a certain medium. The higher the numerical value of the refractive index, the more that light suffers from refraction."
c divided by the index of refraction of the medium = the speed of light in the medium.
It's the speed of light in vacuum divided by the speed of light in that medium.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.

Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s. So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium. Hope I helped!!
Refractive index value of a medium - when it is higher then the speed of light in that medium would become lower. In case of water it travels faster compared to that in glass. In case of diamond the speed is further reduced. Since the refractive index is inversely related to the speed of light in the medium.
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
