Above an angle given by the arcsine of the ratio of refractive indices, known as the critical angle, a light wave is trapped in the medium with the higher refractive index in the "total internal" type of this process.
One type of this phenomenon causes a phase shift in polarized light known as the Goos-Hanchen effect. In that type of this process, an evanescent wave propagates on the boundary of a medium. Under certain conditions, this process will impart a 180-degree phase shift to a wave undergoing it. Above an angle given by the arcsine of the ratio of refractive indices, known as the critical angle, a light wave is trapped in the medium with the higher refractive index in the "total internal" type of this process. In the specular type of this process, the angle of incidence equals the angle at which a light ray departs. For 10 points, name this phenomenon in which waves bounce off a surface.
