Question

an object of height 10cm is placed at a distance of 25cm from a convex lens of focal length 15cm. Find position, nature and size of image

Answer 1

Answer:

Given that,

 Object distance, u=−25cm,Focal length ,f=15cm

From mirror formula- 1/v - 1/u = 1/f

                           =       1/v- 1/25 -1/15

                           =      1/v = 6- 10/150 = -4 /150

                           =       v=-0.0266666667cm
