Question

State two differences between normal reflection and total internal reflection.

Distinguish Between

Solution

Reflection Total Internal Reflection
Takes place in any medium, denser or rarer. Takes place only in a denser medium.
Takes place for any angle of incidence. Takes place only when the angle of incidence is greater than critical angle.
