A compound microscope has an objective and an eye-piece of focal length 1cm and 5cm respectively. The object is located at a distance of 1.05cm close from the objective and form an image 4.17cm close to eye-piece . Find the separation of the lenses and the magnifying power of the microscope (d=25cm)

    solve this in two steps.|dw:1368205614311:dw| apply the thin lens equation one for each lens \[{1\over f}={1\over d_i}+{1\over d_o}\]

    |dw:1368205846491:dw| assume the lenses are separated by a distance of "x" then you get two simultaneous equations and one variable

    "x" = assumed distance between the lenses -> one of the things to calculate
