Real and Apparent Depth

The apparent depth of an object at the bottom of tank filled with a liquid of refractive index 1.3 is 7.7 cm. what is the actual depth of the liquid in the tank ?

See Fig. and answer the following question. a. Find apparent height of the bird. b. Find apparent depth of the fish. c. At what distance will the bird appear to the fish ? d. At what distance will the fish appear to the bird?

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.

The refractive index of water measured by the relation m = (real depth)/ (apparent depth) is found to have values of 1.34, 1.38, 1.32 and 1.36, the mean value of refractive index with percentage error is
