Question

What is TIR in fiber optics?

Answer 1

OK
total internal reflection
When light traveling in an optically dense medium hits a boundary at a steep angle (larger than the critical angle for the boundary), the light is completely reflected. ... This effect is used in optical fibers to confine light in the core.

Answer 2

Hey buddy here is ur answer ....


The critical angle is the angle of incidence above which total internal reflection occurs. The angle of incidence is measured with respect to the normal at the refractive boundary (see diagram illustrating Snell's law ). Consider a light ray passing from glass into air.


hope u like answer ....
