Question

what is the scientific principle behind optical fibre

Answer 1

scientific principle behind optical fibres. An optical fiber is a cylindrical dielectric wave guide that transmitslight along its axis, by the process of total internal reflection.

Answer 2

The scientific principle behind optical fibre:

• Total internal reflection is the principle that optical fibres work on.
• When a light ray strikes the internal surface of an optical fibre cable at a larger angle than the critical angle, the incident light ray reflects in the same medium, and the cycle repeats.
• The light signal goes from one end of the cable to the other in this manner.
