Question

4. Determine the refractive index of benzene if the critical angle of benzene with respect
to air is 42​

Answer 1

Answer:

Let the critical angle be C and refractive index be μ.

C=sin −1 ( μ1 )⟹42 ∘ =sin −1 ( μ1 )⟹sin(42 ∘ )

μ= 0.671

=1.49

is the required refractive index of benzene.
