As per our policy only one question is going to be answered in one url. Derivation of 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
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
