REFRACTIVE INDEX--
1)-Refractive Index is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.
2)-The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations.
3)-The refractive index of a medium is a measure of the reduction in the velocity of light in the medium.
