Question

What is total internal refraction and what are the necessary conditions for it to take place?

Answer 1

when a light travelling from denser medium to rarer medium and incident at an angle greater than the critical angle for the given pair of media the light ray totally reflect back to the same medium following the laws of reflection. this is called total internal refraction.

factors -

1) the light ray should travell from denser to rarer medium

2) the angle of incident should be more than the critical angle for the given pair of media
