How does light travel in fiber optics?

Answer 1

Light travels through fiber optics the same way it travels everywhere else, except when it scrapes against the inside of the cable it bounces off. Sort of like how a matchbox car goes down a plastic track. In fact, just like the toy car, the light will escape from the cable if it has to turn too quickly. The name for this maximum turn angle is called the "critical angle".

This "critical angle" is different depending on what kind of material is in your cable (glass, plastic, metal, etc) as well as what the cable is sitting in (Air, water, space, etc).

Answer 2

Interestingly enough light doesn't "bend" in an optic fibre. It reflects from the inner surface of the fibre back into the fibre material and skips along like that. Imagine a pebble tossed into a long bent and curved pipe down into a mine , it gets to the other end but by ricochetting off the sides, not but following a curved arc down the middle of the pipe

Answer 3

Light travels through fiber optics by reflecting off the walls of the glass or plastic fiber at a shallow angle, known as total internal reflection. This allows the light to bounce along the fiber without escaping, enabling it to travel long distances without significant loss of signal strength. As a result, fiber optics are very effective for transmitting data quickly and efficiently.

Answer 4

People cannot travel through an optical fibre, though light can.

Answer 5

A beam of light is "trapped" inside a fibre-optic cable due to total internal refraction.
