Question

A vessel of depth 2d cm is half filled with a liquid of refractive index μ₁ and the upper half with a liquid of refractive index μ₂. The apparent depth of the vessel seen perpendicularly is
(a) $\bigg \lgroup \frac{\mu_{1}\mu_{2}}{\mu_{1}+\mu_{2}}\bigg \rgroup d$(b) $\bigg \lgroup \frac{1}{\mu_{1}}+\frac{1}{\mu_{2}}\bigg \rgroup d$(c) $\bigg \lgroup \frac{1}{\mu_{1}}+\frac{1}{\mu_{2}}\bigg \rgroup 2d$(d) $\bigg \lgroup \frac{1}{\mu_{1}}+\frac{1}{\mu_{2}}\bigg \rgroup d$
