What are the necessary conditions for total internal reflection to take place?

Question

Verified by Toppr

Answer 1

For total internal reflection to take place (i) light must travel from a denser medium to a rarer medium and (ii) the angle of incidence inside the denser medium must be greater than the critical angle. i.e., $∠ i > ∠ c$ .

Answer 2

For total internal reflection to take place (i) light must travel from a denser medium to a rarer medium and (ii) the angle of incidence inside the denser medium must be greater than the critical angle. i.e.,

∠ i > ∠ c
