Refraction, Glass Slab & Apparent Depth

An ice cube has a bubble inside. When viewed from one side the apparent distance of the bubble is $12\text{ cm}$ . When viewed from the opposite side, the apparent distance of the bubble is observed as $4\text{ cm}$ . If the side of the ice cube is $24\text{ cm}$ , the refractive index of the ice cube is

Show answer and solution

Answer: (a)

Real distances from the two faces add up to the side: $\mu(12 + 4) = 24$ .
$\mu = \dfrac{24}{16} = \dfrac{3}{2}$ .
So the answer is (a).
