Question

The speed of light in a medium is 1.5 x 108
m/s, then what is the refractive index of that
medium?
​

Answer 1

$<h2>ANSWER:</h2>$

Hi,

The speed of light in that medium is

1.5×10^8

Refractive index will be =

Speed of light in air÷speed of light in that medium.

Speed of light in air is 3×10^8

=3×10^8/1.5×10^8

=3/1.5

=30/15

=2

So, it's refractive index is 2
