A 6 cm tall object is placed perpendicular to the principal axis of a convex lens of focal length 25 cm. The distance of the object from the lens is 40 cm.

By calculation determine :

(a) the position and

(b) the size of the image formed.

Given, Height of an object h0 = 6 cm

Focal length of a lens, f = 25 cm

Distance of an object, u = - 40 cm

(a) Using lens formula,

(b) Magnification
