Total internal reflection
When light travels from an optically denser medium to a rarer medium hits their boundary at a steep angle (larger than the critical angle for the boundary), the light gets completely reflected back. This is called total internal reflection. This effect is used in optical fibers to confine light within the core.
Optical Fibre Cable:
● Optical Fibre Cable is made of glass fibre material. The cable wire is made up of concentric circles of this glass fibre. The inside layer is called core and outside layer is called cladding.
● The glass fibre core and cladding each have different refractive indices which bends the incoming light at a certain angle. This continuous refraction from different concentric circles helps reach the critical angle beyond which Total internal reflection of light takes place at cladding.
● This total internal reflection helps in confining light to the core region.
Application :
Fiber optics are also commonly used in telecommunication services such as internet, television and telephones

Optucal fiber cabels works on the principle of total internal reflection. Instead, the lifht is reflected back over and over because of total internal reflection until it emerges at the other end of the cable. Fiber optic cables are used to transmit data and to illuminate objects and areas that are hard to get light to.
