The phenomenon used in optical fibre for transmission of light energy is

Answer & Solution

Answer: (Detailed Solution Below)

Option A: Total internal reflection

Detailed Solution:

The correct answer is “Total internal reflection”.

The phenomenon used in optical fiber for the transmission of light energy is Total Internal Reflection.

In optical fibers, light is transmitted through the core by continuously reflecting off the walls of the fiber. This process occurs because the angle of incidence of the light is greater than the critical angle, allowing the light to be totally internally reflected and travel along the fiber without escaping.
