The apparent depth of a needle laying at the bottom of the tank, which is filled with water of refractive index `1.33` to a height of `12.5` cm is measured by a microscope to be `9.4 cm`. If water is replaced by a liquid of refractive index `1.63` upto the same height. What distance would the microscope have to be moved to focus on the needle again ?

A tank is filled with water to a height of 12.5 cm . The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm . What is the refractive index of water ?
