Question

When the distance between the object and the screen than 4f,we van obtain he image of the object on the screen or the position of a convex lens of focal length f.It is called displacement method .In one case the image is magnified if $I_{2} a n d I_{2}$ be the sizes of the two images.then the size of the object is:

A

(I_{2} + I_{2}) / 2
