Source: FiberLabs Inc. Total Internal Reflection Total Internal Reflection Understanding Total Internal Reflection Total internal reflection occurs when light is fully reflected at the interface between two transparent media if the angle of incidence is greater than the critical angle. The critical angle is determined by the refractive indices of the two media involved. Applications
