Fundamental principle behind the propagation of light in dielectric waveguides and optical fibers is
Show Hint
Optical fibers use total internal reflection to guide light along the core, making them efficient for long-distance communication.

- Diffraction
- Absorption
- Refraction
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The propagation of light in dielectric waveguides and optical fibers relies on the principle of total internal reflection. This occurs when the light is reflected off the core-cladding interface within the fiber, allowing the light to travel long distances with minimal loss.
