Question

A substance has a critical angle of 45°for yellow light, what is its refractive index?

Ans=...
Given.
Critical angle ic=45°
Refractive index( miu) =?
We know that..
M(Miu) =1/sinic=1/sin45°
M=√2/1=√2
Therefore. Refractive index of a yellow light is √2..

Answer 1

Given, Critical angle ic=45°

Refractive index( miu) =?

We know that,

M(Miu) = 1/sinic = 1/sin45°

M = √2/1 = √2

Therefore, Refractive index of a yellow light is √2.
