MCQ

Immiscible transparent liquids $A, B, C, D$ and $E$ are placed in a rectangular container of glass with the liquids making layers according to their densities. The refractive index of the liquids are shown in the adjoining diagram. The container is illuminated from the side and a small piece of glass having refractive index $1.61$ is gently dropped into the liquid layer. The glass piece as it descends downwards will not be visible in

A
Liquid $A$ and $B$ only
✓
Liquid $C$ only
C
Liquid $D$ and $E$ only
D
Liquid $A, B, D$ and $ E$

✓

Answer

Correct option: B.

Liquid $C$ only

b
(b) Refractive index of liquid $C$ is same as that of glass piece.

So it will not be visible in liquid $C$.
