​

Answer 1

Answer:

FERMAT'S PRINCIPLE

Step-by-step explanation:

Answer 2

Answer:

Concept:

Light travelling in an Optical fibre follows  Total internal reflection.

Snell's law reveals the relationship between the directions of travel in the two media.

Step-by-step explanation:

It makes no difference if the cable is bent as optical fibres are used to transfer light along curved paths. Total internal reflection is the basis for optical fibre transmission. We must keep in mind that light travels in a zigzag pattern rather than bending via optical fibre.

Total internal reflection is essential to the functioning of optical fibres. An optical fibre is a thin, glass rod of superior quality. Light or infrared enters at one end and exits at the other after undergoing numerous total internal reflections. As the light enters the optical fibre, observe how it refracts in the direction of the normal.
