Dear Anil,

convex lens formula

 

Let AB represent an object placed at right angles to the principal axis at a distance greater than the focal length f of the convex lens. The image A1B1 is formed beyond 2F2 and is real and inverted.

OA = Object distance = u

OA1 = Image distance = v

OF2 = Focal length = f

OAB and OA1B1 are similar

But we know that OC = AB

 the above equation can be written as

From equation (1) and (2), we get

Dividing equation (3) throughout by uvf

Best Of luck
