Question

Formula of critical angle with respect to refractive index

Answer 1

Answer:

The critical angle can be calculated by taking the inverse-sine of the ratio of the indices of refraction. The ratio of nr/ni is a value less than 1.0. In fact, for the equation to even give a correct answer, the ratio of nr/ni must be less than 1.0.

Answer 2

Answer:

The critical angle can be calculated by taking the inverse-sine of the ratio of the indices of refraction. The ratio of nr/ni is a value less than 1.0.
