Answer 2

The answer should be option (B) u2>u1 >u3.

Explanation :

It can be observed from the figure that when light enters from u1 to u2 it bends towards the normal. Which means R.I of u2>R.I of u1. Next the light enters from u2 to u3 it bends away from the normal. Which means again R.I of u2 >R.I of u3 . From these two scenarios we can conclude that u2 has the highest refractive index

Therefore u2>u1>u3
