fiber optic cables are made out of many concentric layers of transparent material (usually glass or plastic), each with a slightly different index of refraction. How can these transparent cables keep light inside?

Answer: Transparent cables can keep light inside by the phenomenon of total internal reflection.

Explanation:

Optical fibers are often made from glasses or plastics.

when light rays falls on the glass or plastic with an angle greater than the critical angle, we have what is known as TOTAL INTERNAL REFLECTION

The total internal reflection causes the fibre to act as a wave guide. For a good glass or plastic when the rays of light falls, the ray converges and for a bad plastic or glasses, the rays are dispersed.

Therefore, transparent cables can keep light inside because of total internal reflection.

Transparent fiber optic cables (FOCs) can keep light inside due to total internal reflection.

What is a cable?

A cable can be defined as a type of wired connector which are either made of glass, plastic or copper and they are typically used for connecting one network device to another, so as to form a computer network and enable the continuous transmission of data between them.

In Computer technology, fiber optic cables (FOCs) are commonly produced through the use of several concentric layers of transparent material such as glass or plastic, with each having a slightly different index of refraction for light waves.

In conclusion, total internal reflection is an optical phenomenon that makes it possible for transparent fiber optic cables (FOCs) to keep light inside because it allows the complete reflection of a ray of light within the glass or plastic (medium) used.
