Total internal reflection is a phenomenon that happens when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, the wave cannot pass th...

When light is traveling from a material with a higher index of refraction into one with a lower index of refraction, if the angle of incidence exceeds the critical angle, the light is totally reflected. See also: Refractive Index.

Complete reflection of a beam of light that occurs from the surface of an optically `less dense` material. For example, a beam from an underwater light source can be reflected from the surface of the water, rather than escaping through the surface. Total internal reflection can only happen ...
