    For a compound microscope, the focal lengths of object lens and eye lens are\[{{f}_{0}}\] and \[{{f}_{e}}\] respectively, then magnification will be done by microscope when :

    A)  \[{{f}_{0}}={{f}_{e}}\]                  

    B)  \[{{f}_{0}}>{{f}_{e}}\]

    C)  \[{{f}_{0}}<{{f}_{e}}\]  

    D)         none of these

    Correct Answer: C

    Solution :

    Magnification will be done by compound microscope only when focal length of object lens is less than focal length of eye lens. \[\therefore \]                  \[{{f}_{0}}<{{f}_{e}}\]
