Explanation:

Given:

A convex lens of focal length 15 cm formed a real image at a distance of 20cm from its optical centre .find the position of the object.Is the image formed by the lens magnified or diminised?

To find:

Given that u=−15cm f=20cm 

Formula:

  • By lens formula 

  •                       f1=v1−u1

  •                        v1=101−201

  •                     ⇒v=20cm

Required answer:-

The image gets formed at 20 cm to the right of the lens and it will be diminished, inverted and real in nature.
