Figure illustrates an aligned system consisting of three thin lenses. The system is located in air. Determine: (a) the position of the point of convergence of a parallel incoming from the left after passing through the system, (b) the distance between teh first lens and a point lying on the axis to the left of the system, at which that point and its image are located symmetrically with respect to the lens system.
