Fiber optics cable used in communication, works on the principle of
-
- regular reflection of light
- diffuse reflection of light
- refraction of light
- total internal reflection of light
- regular reflection of light
Correct Option: D
The use of a long strand of plastic (or other material such as glass) to pipe light from one end of the medium to the other is the basis for modern day use of optical fibers. Since total internal reflection takes place within the fibers, no incident energy is ever lost due to the transmission of light across the boundary.
