An оbject is plаced 6 cm in frоnt оf а converging lens hаving a focal length of 1 cm. A second identical converging lens is located 5 cm behind the first lens. How far from the first lens is the first image formed? [di1] (use equations and show work) What is the magnification for the rays passing through the first lens? [M1](use equations and show work) How far from the second lens is the image formed by the second lens? [di2](use equations and show work) What is the magnification for the rays passing through the second lens? [M2] (use equations and show work) The final image of this system is [final]       (real, virtual, not formed) The final image of this system is  [inup]      (inverted, upright, not formed)    The final image of this system is    [mag]    (bigger, smaller, the same, not formed)
