Question

Optical fiber guides light mainly by:

RankGuru · Accepted Answer

An **Optical Fiber** consists of a core of higher refractive index surrounded by a cladding of lower refractive index.
- Light entering the core at a small angle hits the core-cladding interface at an angle greater than the critical angle.
- It undergoes repeated **Total Internal Reflection (TIR)**, traveling long distances with minimal loss even if the fiber is bent.
