In a vessel, as shown in Figure., point P is just visible when no liquid is filled in vessel through a telescope in the air. When liquid is filled in the vessel completely, point Q is visible without movint the vessel or telescope. Find the refractive index of the liquid.

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.

In the above problem, now a liquid is poured into the vessel and filled up to OQ. The central bright fringe is found to be at Q. The refractive index of the liquid is

In the previous problem what will be refractive index of the liquid so that point E is visible (PE=R//3) through the telescope in air when the vessel is filled with liquid completely, without moving the telesope and vessel.

The height of a vessel is 15 cm . Liquid is poured into the vessel such that the surface of the liquid remains 5 cm below the vessel's top. On seeing from above the depth of the liquid appears to be half. Calculate the refractive index of the liquid.

There is a tiny LED bulb, at the centre of the bottom of a cylindrical vessel of diameter 6 cm. Height of the vessel is 4 cm The beaker is filled completely with an optically dense liquid. The bulb is visible from any inclined position but just visible, if seen along the edge of the beaker. Determine the reflective index of the liquid.
