1.	A microscope is focussed on a stone, tied to a string, lying at the bottom of an empty beaker. Now some oil is poured into it until it reaches to a height 'y' cm in the beaker. Therefore the microscope needs to be moved to 'x' cm to now focus at the stone clearly. Calculate the absolute refractive index of oil in terms of 'x' and 'y'.
