Question

What is total internal reflection.

Answer 1

Answer:

Angle of incidence in denser medium for which angle of refraction is 90 degree know as critical angle..

if value of incidence angle is more than critical angle then light Ray turns back to same medium (danser) this phenomenon Called total internal refraction..

To condition for total IR

1. light should travel from danser to rare medium

2. the value of angle of incidence should be more than critical angle

Answer 2

Answer:

Here is your answer..

Explanation:

Total Internal Reflection is the phenomenon that makes the

water-air-surface in a fish-tank look like a perfectly silvered mirror when viewed from below the water level.
