The velocity of light in a material medium is `2 xx 10^(8) ms^(-1)`. The refractive index of the medium

A

`1.5`

B

2

C

`1.33`

D

`1.25`

Text Solution

Verified by Experts

The correct Answer is:
A
Refractive index of medium
=`("speed of light in vacumm")/("speed of light in the medium" )=(3xx10^(8))/(2xx10^(8))=1.5`
