Question

Determine the refractive index of benzene if the critical angle is 42.

Answer 1

let us take the refractive index of benzene as x
so x= 1/sinc
       = 1/0.6691
       = 1.51

Answer 2

Answer:

Critical angle of benzene=42°. We know that. sin c = 1/Refractive index. sin 42°= 1/Refractive index of benzene. Refractive index of benzene=1/sin42° = 1/0.6691 =1.49
