Question

if an angle of incidence in a denser medium is equal to the critical angle the angle of refraction is

Answer 1

In our introduction to TIR, we used the example of light traveling through water towards the boundary with a less dense material such as air. When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of90-degrees.
