» Ray Optics » Total Internal Reflection

Appeared in Year: 2006

Assertion-Reason▾

Assertion (Ꭺ)

In optical fiber, the diameter of the core is kept small.

Reason (Ꭱ)

This smaller diameter of the core ensures that the fiber should have incident angle more than the critical angle required for total internal reflection.
