What is meant by the term total internal reflection?

What is meant by the term total internal reflection?

Answer : When a ray of light from denser medium enters a rare medium in such a way that angle of incident is greater than critical angle, then the ray is reflected totally inside and does not emerge out from the denser medium.This phenomenon is called total internal reflection.
