Question

Total Internal reflection happens only when the light is traveling from an optically denser medium to an optically rarer medium.

• A. True
• B. False

Answer 1

The correct option is A

True

Total Internal reflection happens only when the light is traveling from an optically denser medium to an optically rarer medium, as it is possible only when the angle of incidence is greater than the critical angle for the pair of media. It is maximum in the denser medium.
