Question

How can one increase the magnification of a real image created by a single biconvex lens?

Step 1

By convex lens are the combination of two convex lenses in a spherical form, In most cases the two simple spherical convex lenses are of same radius.

Step 2

If the object is placed at twice of the focal length same magnification will be obtained. The equation of magnification is m =-v/u. This equation implies that to increase magnification image distance should be greater than object distance

Step 3

Image distance can be increased by placing object between center of curvature and pole. In such case image will be formed beyond the center of curvature of other side of the lens. But placing between focus and pole will leads to the form...
