Question

write relationship between absolute refractive index of a medium and speed of light in vacuum

Answer 1

here is ur ans
n(refractive index) =c(speed of light in air or vacuum )/v(speed of light in given medium)

Answer 2

Answer:

The ratio of the speed of light in vacuum to the speed of light in air is known as the refractive index of a medium.

Explanation

• The speed at which light travels through things like glass or air is slower than c, just as the speed at which radio waves travel through wire cables is slower than c.

• The ratio of the speed of light in vacuum (or air) to the speed of light in that medium is the refractive index of that medium. As a result, the speed of light in such a media is slower than that of light in a medium with a lower refractive index.
