Question

______is the basic principle behind the optical fibre

Answer 1

Answer:

We can say Optical Fibre works on the principle of total internal Reflections. It is a power full Phenomena which is used in optical fibre cable to transmit data from one place to another place. Total Internal reflection is complete reflection.

Answer 2

Answer:

Optical fibre works on total internal reflection principle.

Explanation:

Optical fibre works on principle of total internal reflection. When light ray strikes at the internal surface of optical fibre cable called such the incidence angle is greater than the critical angle, then incident light ray reflects in the same medium, and this phenomenon repeats.
