Question

Which among the following are used in transport communication signals through light pipes?

• A. Plane mirrors
• B. Concave lenses
• C. Prisms
• D. Optical fibers

Answer 1

The Correct Option is D

• Optical fibers are special flexible fibers that carry light signals using the principle of total internal reflection.
• They are commonly used in telecommunication and internet data transmission due to their efficiency and high speed.
• Other options like plane mirrors, concave lenses, and prisms are not practical for long-distance signal transmission through light pipes.

Correct Answer: Optical fibers
