Two transparent media A and B are separated by a plane boundary. The s – InterviewSolution

1.	Two transparent media A and B are separated by a plane boundary. The speed of light in medium A is 2.0×108 ms−1 and in medium B is 2.5×108 ms−1. The critical angle for a ray of light going from medium A to B is :
Answer» Two transparent media $A$ and $B$ are separated by a plane boundary. The speed of light in medium $A$ is $2.0 \times 10^{8} {ms}^{- 1}$ and in medium $B$ is $2.5 \times 10^{8} {ms}^{- 1}$ . The critical angle for a ray of light going from medium $A$ to $B$ is :
