364902 A fish in water (refractive index \(n\)) looks at a bird vertically above in the air. If \(y\) is the height of the bird and \(x{\rm{ }}\) is the depth of the fish from the surface, then the distance of the bird as estimated by the fish is

364903 A vessel is half filled with a liquid of refractive index \(\mu\). The other half of the vessel is filled with an immiscible liquid of refractive index \(1.5 \mu\). The apparent depth of the vessel is \(50 \%\) of the actual depth. Then \(\mu\) is

364904 A plane glass slab is kept over various coloured letters, the letter which appears least raised is

364905 A concave mirror of radius \(R\) is kept on a horizontal table (figure). Water (refractive index \( = \mu \) ) is poured into it upto a height \(h\). What should be the distance of a point object from surface along principal axis so that its final image is formed on itself. Consider two cases.
