A microscope is focussed on a point at the base of an empty vessel. Now water `(mu = (4)/(3))` is poured in it up to a height of 4 cm. Next a light oil `(mu = (4)/(3))` is placed on water up to a height of 2 cm. The oil does not mix with water. In this condition by how much should the microscope be raised to focus the particular point?

A cross mark at the bottom of an empty vessel is focussed with the help of a vertical microscope. Now water ("refractive index" = (4)/(3)) is poured in the vessel. The height of water in the vessel is 4cm. Another lighter liquid which does not mix with water and whose refractive index is (3)/(2) , is poured on water. The height of the liquid is 2 cm. How much should the microscope be raised vertically to focus the mark again?
