The angular magnification of a simple microscope can be increased by increasing :- 1 focal length of lens 2 size of object 3 aperture of lens 4 power of lens

The magnifying power of simple microscope can be increased if we use a lens of

Assertion : Magnification power of microscopes can be decreeased by increasing the focal length of the lens used. Reason : Due to constructional limitations , the focal length of lens cannot be decreased beyond certain unit.

In a simple microscope, the object is placed within the focal length of the convex lens.

If there is an increase or decrease in the focal length of a lens, what will be the effect on the power of the lens ?

In a simple microscope to obtain higher magnification, the focal length of convex lens should be ________-

If the focal length of objective lens is increased then magnifying power of

If the focal length of objective lens is increased then magnifying power of the
