While determining the refractive index of a liquid experimentally, the microscope was focussed at the bottom of a beaker, when its reading was 3.965 cm. on pouring liquid upto a height 2.537 cm inside the beaker, the reading of the refocussed microscope was 3.348 cm. Find the refractive index of the liquid.

To determine the refractive index of a liquid experimentally, a mark is made on the beaker and a microscope was focussed on it, giving a reading of 3.42 cm. On pouring liquid till a height 2.68 cm inside the beaker, the reading of refocussed microscope is 3.38 cm. Calculate 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.

A microscope is focussed on a coin lying at the bottom of a beaker. The microscope is now raised up by 1 cm . To what depth should the water be poured into the beaker so that coin is again in focus ? (Refration index of water is 4//3 )

A travelling microscope is focussed on to a scratch on the bottom of a beaker. Water of refractive index (4)/(3) is poured in it. Then the microscope is to be lifted through 2 cm focus it again. Find the depth of water in the beaker.
