if the ray gets incident on an angle greater than this value it gets reflected in the same medium.... this is called total internal reflection. The critical angle is this angle of incidence above which the total internal reflection occurs.

Explanation:

The angle of incidene corresponding to which angle of refraction becomes 90º is called critical angle. Conditions:i Light should travell from denser medium to rarer mediumii For total internal reflection angle of incidence must be greater than critical angle.
