A coin is kept at the bottom of a vessel having two immersible liquids having R.I. $\frac{4}{3}$ and $\frac{5}{3}$ and layer thickness 8 cm and 15 cm. Find apparent depth (in cm) when it is seen normally.

Answer:

Solution:

Apparent depth seen normally through both liquid layers: $d_{app} = \frac{8}{4/3} + \frac{15}{5/3} = 6 + 9 = 15 cm$
