Question

Conditions for internal reflection is:

• A. Light must travel from rare to denser medium
• B. The angle of incidence should be greater than the critical angle for the given pair of media
• C. Both
• D. None

Answer 1

The correct option is B The angle of incidence should be greater than the critical angle for the given pair of media

For internal reflection to occur, light must travel from denser to a rarer medium. The angle of incidence should be greater than the critical angle for the given pair of media.
