Total internal reflection in optical fibres
Optical fibres use the principle of total internal reflection. The light ray incident at an angle greater than critical angle undergoes T.I.R. and stays trapped inside the optical fibre. This technique of transmitting information using light energy is very efficient as the 100% of the energy get reflected at the interface of dense-to-rare medium.
