प्रश्न
Write an expression for the magnifying power of a simple microscope. How can it be increased?
उत्तर
Is the ratio of the angle of the image subtended at the eye to the angle subtended by the object at the eye when lying at least a distance of distinct vision.
m = 1 + `D/f` where f is the focal length of the lens.
One way to get more magnifying power is to use a lens with a shorter focal length.
