Geometrical Optics

Question

Which of the following is used in optical fibres?

Accepted Answer

Option A. Optical fibers work on the principle of total internal reflection. When light is transmitted through the fiber, it is reflected off the inner walls of the fiber in such a way that it remains within the fiber, allowing it to carry the light signal over great distances with minimal loss.
