Question

explain refractive index of material


and how was my status

Answer 1

The ratio of the velocity of light in a vacuum to its velocity in a specified medium is called it's refractive Index.It has no units.

For example-refractive index of water is 1.333, meaning that light travels 1.333 times as fast in vacuum as in water.

Answer 2

Refractive Index. The refractive index, n, of a material is defined as the ratio of the velocity of light in a vacuum relative to the velocity of light passing through that material.


and I don't think ur dp is good
