Question

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. According to Snell's Law, C=sin −1 ( μ1 )⟹42 ∘ =sin −1 ( μ1 )⟹sin(42 ∘ ) μ= 0.671=1.49is the required refractive index of benzene
