Question

what is refractive index????? ​

Answer 1

$\huge\fcolorbox{black}{lime}{AnsweR:}$

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.

$\bold{ExplanatioN:}$

$\large\boxed{n=\frac{c}{v} }$

n = refractive index ,

{c} = speed of light ,

{v} = phase velocity of light .
