Question

The speed of light on a transparent medium is o. 5 timesof its speed in vacuum then qhat is its refractive index

Answer 1

Answer:

R.I of medium = 2

Explanation:

Given : v = 0.5 x c

           ∴ c/v = 1/0.5 = 2

R.I of medium $n_{m}$ = $\frac{Speed of light in vacuum}{speed of light in medium}$ = $\frac{c}{v}$

                             = 2
