Question

Optical fiber works on the principle of

A) Scattering B) interference
C) total internal reflection D) refraction

Answer 1

Answer:

C)Total internal reflection.

It is used to transmit light energy over long distances without losses in energy.

Answer 2

Optical fiber works on the principle of total internal reflection.

The total internal reflection is the phenomena in which the complete reflection of a light ray reaching an interface with a less dense medium when the angle of incidence exceeds the critical angle.
