Asked by paulh.kvhvf | 23 May, 2010, 08:07: PM
answered-by-expert Expert Answer

If the ray is incident at critical angle, at the interface it'll no longer will be refracted into the other medium but will be reflected back into the same medium, it's called total internal reflection and occurs at an angle of incidence called critical angle of incidence.
