Two rays travelling parallel to the principal axis strike a thick large plano-convex lens having a refracive index of `1.60`.If the spherical face has a radius of curvature of magnitude `20.0`cm and th two rays are `h_(1)=0.500cm`and `h_(2)=12.0cm` from the principal axis ,find the difference in the positions where they cross the principal axis .Assume that the ray incident at height `h_(2)`is incident at the periphery.
