Solution
the power of the lens
For a simple microscope in normal adjustment, the object is placed at a distance equal to f (the focal length) from the lens, And the angular magnification is given by the relation

For u < f , m =D/f +1.
Power of the lens = 1/f
Angular magnification depends on power.
