Question

the absolute refractive index of a transparent medium is 5/3.find the speed of light in the medium

Answer 1

What is the spped of light in a transparent medium which has a refractive index of 1.7?(the speed of light in vaccum is 3 x 108 m/s.)

this is just example

Since, μ = c/v

Given , ​μ = 1.7

μ X v = c

v = c/​μ = 3 × 1081.7 = 1.76 × 108 m/s

I hope this will help you
