Answer:
Step-by-step explanation:
The functioning of optical fibers, which are plastic fibers, is dependent on the phenomena of total internal reflection. These are used to carry optical signals from one location to another and are made up of long, hair-thin strands of high-quality quartz or glass that are coated in glass that has a slightly lower refractive index.
Core, cladding, and buffer coating make up the structure.
Total internal reflection does not result in any intensity loss; the outgoing beam has the same intensity as the incident beam.
Light pipe is the name for an arrangement of optical fibers.
Applications for fibers include transmission and reception of electrical impulses in communications as well as optical and medical evaluation.
