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

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

Assertion (A): Convex lens behaves like a simple microscope. Reason (R): For larger magnifying power, the focal length of convex lens should be small.

A convex lens of focal length 6.25cm is used as a simple microscope. To obtain maximum magnification, the object distance should be

The image obtained while finding the focal length of a convex lens is ……………… .

To obtain a magnification of, -0.5 with a convex lens, the object should be placed:

A lens of power 16D is used as a simple microscope. In order to obtain maximum magnification, at what distance from the lens

In order to obtain a magnification of, -0.75 with a convex lens of focal length 8 cm, the object should be placed:

Magnifying power of a simple microscope is inversely proportional to the focal length of the lens. What then stops us from using a convex lens of smaller and smaller focal length and achieving greater and greater magnifying power ?
