the angle of incidence beyond which rays of light passing through a denser medium to the surface of a less dense medium are no longer refracted but totally reflected.
e,g
it means when a ray from a source comes from water to air it goes deflected from its origanal straight line path and get deflected or get bend and
or critical angle is the angle where refration get stop and reflection get states
