Question

Consider the figure and select the correct statements from the following

• A. Since, sin $i_i\ne sin{i}_2$, the emergent ray in medium (3) is parallel to the incident ray in medium (1)
• B. The optical density of medium (3) is less than the optical density of medium(1)
• C. The optical density of medium (2) is greater than that of both media (1) and (3)
• D. Both (2) and (3)

Answer 1

The correct option is D Both (2) and (3)

Since in the figure $i_1\ne i_2$.Hence, ${\mu }_1\ne {\mu }_3$ and we can observe $i_2.>i_1$. Hence ${\mu }_1>{\mu }_3$. As light bends more away from the normal when the optical density of medium rarer and viseversa.
