    The lens equation is given as:

    , where p = object distance, q = image distance

    From the graph, at p = 10 cm, M = 0.6 (approx)
    Therefore, 0.6 = -q/10, which gives q = -6 cm
    Therefore,
    Therefore, f = -15 cm.
    Now, at p = 35 cm,
    , therefore, q = -21/2 = -10.5 cm
    Hence M = -q/p = 10.5/35 = 0.3. ...

    Solution Summary

    The optics and magnifications on objects are examined.
