Question

explain refractive index...​

Answer 1

Explanation:

Index of Refraction

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

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.

Explanation:

n=c/v

n = refractive index

{c} = speed of light

{v} = phase velocity of light
