Answer: Option D For total internal reflection TIR to occur, two conditions must be present: 1. light must be travelling from a optically...

Overview of Total Internal Reflection (TIR) Explanation of the various stages:

Solutions: a) Refraction     b) 48.6o     c) c = 41.8o     e) 70o d) Total internal reflection has occured, as the angle of incidence is...

Solutions: a) 38.8o      b) 41.8o c) 51.2o . The ray does not emerge as total internal reflection has occurred. The angle of incidence is...
