Question
What is the relation between critical angle and refractive index of a material?
Solution
The relation between critical angle and the refractive index of a material is,
μ = sin ic or n21 = sin ic
where,
n21 is the refractive index of rarer medium 1 with respect to denser medium 2 and,
ic is the critical angle.
μ = sin ic or n21 = sin ic
where,
n21 is the refractive index of rarer medium 1 with respect to denser medium 2 and,
ic is the critical angle.
