Question

Match the following: A right angled prism of refractive index $\mu_{1}$ is placed in a rectangular block of refractive index $\mu_{2}$, which is surrounded by a medium of e refractive index $\mu_{3}$, as shown in the figure. A ray of light ‘e’ enters the rectangular block at normal incidence. Depending upon the relationships between $\mu_{1}$, $\mu_{2}$ and $\mu_{3}$, it takes one of the four possible paths ‘ef’, ‘eg’, ‘eh’, or ‘ei’. Match the paths in Column I with conditions of refractive indices in Column II.
Column I
(p) e $\rightarrow$ f
(q) e $\rightarrow$ g
(r) e $\rightarrow$ h
(s) e $\rightarrow$ i

Column II
(1) $\mu_{1}$>$\sqrt{2}$$\mu_{2}$
(2) $\mu_{2}$>$\mu_{1}$ and $\mu_{2}$>$\mu_{3}$
(3) $\mu_{1}$=$\mu_{2}$
(4) $\mu_{2}$<$\mu_{1}$<$\sqrt{2}$$\mu_{2}$ and $\mu_{2}$>$\mu_{3}$.
