In the structure of fiber, the light is guided through the core due to total internal:
Correct answer: A. Reflection
- A. Reflection
- B. Refraction
- C. Diffraction
- D. None of these
Explanation
Optical fibre guides light by total internal reflection at the boundary between its denser core and less-dense cladding. Refraction changes direction at a boundary, but it is not the guiding principle named here.
