प्रश्न
To increase the angular magnification of a simple microscope, one should increase ______.
विकल्प
the focal length of the lens
the power of the lens
the aperture of the lens
the object size
उत्तर
To increase the angular magnification of a simple microscope, one should increase the power of the lens.
Explanation:
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
m = `"D"/"F"`
For u < f, m = `"D"/"f" + 1`
Power of the lens = `1/"f"`
Angular magnification depends on power.
