Relation between critical angle and refractive index of the medium xl worker denoted with symbol, Фc.
In this solution, snell's law (the ratio of sin incidence to sin refraction of wave is constant when it crosses through two available media) is appointed to find out relation.
μ1sini = μ2sinr
μsinФc = 1. sin90
sinФc = 1/μ
Фc = inverse sin(1/μ)
