Question

relation of refractive index ,speed of light and density of medium​

Answer 1

Answer:

Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations.......

Answer 2

Hey mate ,

RI = C / V

Where C is speed of light in vaccum

and V stands for speed of light in given medium

Also ,

The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material. The refractive index is a measurement of optical density.
