Vedclass · Answer

(A) Total internal reflection $(TIR)$ is a phenomenon that occurs when light travels from a denser medium to a rarer medium.For $TIR$ to take place, two conditions must be satisfied:$1$. The light ray must travel from an optically denser medium to an optically rarer medium.$2$. The angle of incidence $(i)$ must be greater than the critical angle $(i_{C})$ for the given pair of media.Therefore, the correct statement is that the ray travels from a denser medium to a rarer medium and $i > i_{C}$.

For total internal reflection to occur, which one of the following is the correct statement? $(i = \text{angle of incidence}, i_{C} = \text{critical angle})$.
