QUESTION #36 Total Internal Reflection
Consider light travelling from a medium A to medium B separated by a plane interface. If the light undergoes total internal reflection during its travel from medium A to B and the speed of light in media A and B are 2.4 times 10^8text m/s and 2.7 times 10^8text m/s respectively, then the value of critical angle is:
