Real and Apparent Depth

The apparent depth of an object O from AB is

Using formula of spherical surface or otherwise, find the apparent depth of an object placed 10cm below the water surface, if seen near normally form air.

In Fig. , find the apparent depth of the object seen below surface AB.

A vessle of depth d is first filled to ( (2)/( 3))^(rd) of its depth with a liquid of refractive index ( 3)/( 2) and the rest of the vessel is filled with a liquid of refractive index ( 4)/( 3) . What is the apparent depth of the inner surface of the bottom of the vessle.
