Question

An equiconvex lens, with radii of curvature of magnitude 10 cm each, is put over a liquid layer poured on top
of a plane mirror. Asmall needle, with its tip on the principal axis of the lens, is moved along the axis until its
inverted real image coincides with the needle itself. The distance of the needle, from the lens, is measured to
be 15 cm
On removing the liquid layer, and repeating the experiment the distance is measured to be 10 cm
Given that the two values of the distance measured represent the force length values in the two cases,
calculate the refractive index of the liquid
