The phenomenon of total internal reflection of light.
Class 12 Physics
Chapter 9 Ray Optics and Optical Instruments Session 2024-2025.
The working of optical fibers is based on the principle of total internal reflection. When light travels through the core of the fiber, it is reflected entirely at the core-cladding interface, allowing efficient transmission over long distances.
