Question

How to find refractive index ? explain.

Answer 1

RF=light travel in rarer medium/light travel in danser medium

it is in the ratio so it have no unit

ok

Answer 2

there are many ways from which we can find the index reflective-

1. by determining the speed of light in the analysed medium.

2. using our snell low calculater.

3. divide the speed of light by this value...

4. the obtained value is the reflective index of the medium..

hope it will help you
