On heating a liquid, the refractive index generally

The apparent depth of a liquid in a vessel is 15 cm, when its real depth is 20 cm. find the refractive index of the liquid.

On heating a liquid the refractive index generally:

A point source S is placed at the bottom of a tranparent block of height 10mm and refractive index 2.72. It is immersed in a lower refractive index liquid as shown in the figure. It is found that the light emerging from the block to the liquid forms a circular bright spot of diameter 11.54 mm on the top of the block. The refractive index of the liquid is
