Question

In a ice cube of thickness 24 cm, has bubbles trapped in it as shown in figure. If apparent side are 12 cm and 4 cm from side 1 and side 2 respectively, then refractive index of ice cube is

• A. $\frac{4}{3}$
• B. $\frac{3}{2}$
• C. 2
• D. 2.4

Answer 1

Answer: (B)

$\frac{3}{2}$

Answer 2

The correct option is (B): $\frac{3}{2}$

$\frac{I}{\mu}=12+4=16cm$

$\frac{24}{16}=\mu$

$\Rightarrow \mu=\frac{3}{2}$
