You given two planoconvex lenses of focal lengths `0.03`m and `0.05`m and asked to design an eye-piece free from chromatic aberration. Explain how you will achieve it . Calculate the equivalent focal length of the eye-piece formed and its magnifying power if it is used by a person for whom least distance of distinct vision is `0.25`m. Will your eye-piece be free from spherical aberration?
