Question

if the refractive index of denser medium is 1.5 then what is the value of critical angle?​

Answer 1

I hope u understood.

this is the answer.

Answer 2

Given,

Refractive Index of Denser Medium = 1.5 or, 3/2

sin C = 1/μ

.... 'C' is the Critical Angle,

sin C = 1/(3/2)

sin C = 2/3

sin C = sin 42°

C = 42°

I hope this helps.
