A vessel of depth $t$ is half filled with a liquid having refractive index $n_{1}$ and the other half is filled with water of having refractive index $n_{2}$ . The apparent depth of the vessel as viewed from top is

Options:

Answer:

Solution:

The apparent depth is given by $I^{'} = \frac{t _{1}}{n _{1}} + \frac{t _{2}}{n _{2}} = \frac{t /2}{n _{1}} + \frac{t /2}{n _{2}} = \frac{t ( n _{1} + n _{2} )}{2 n _{1} n _{2}}$
