How is the critical angle related to the refractive index of a medium?

Solution:

{}_{a}\mu_{m}

is the refractive index of the denser medium with respect to the rarer medium and '

c

' is the critical angle for the pair of media then the relation between them is

{}_{d}\mu_{m} = \frac{1}{\sin C} = \csc C
