Total Internal Reflection: Practice Problem & Solution

Optical fibre are based on: (2001)
Total internal reflection
Less scattering
Refraction
Less absorption coefficient

Solution Explained:

To solve this problem, we apply the core principles of Total Internal Reflection. Understanding the underlying formula is key to arriving at the correct answer below:

Optical fibers work on the principle of total internal reflection. Light entering the fiber strikes the core-cladding interface at an angle greater than the critical angle, reflecting entirely within the core.
