Hey,
For light passing through some medium, if the angle of incidence exceeds the critical angle, is there always total internal reflection such that the angle of reflection = angle of incidence? Or can there be a reflected angle which isn't equal to the angle of incidence?
Thanks

If the angle of incidence exceed the critical angle, then there is no refraction - only reflection occurs. Thus, the Law of Reflection applies and the angle of incidence equals the angle of reflection.
