Question

Draw ray diagrams to represent the nature, position and relative size of the image formed by a convex lens for the object placed:
(a) at 2F₁.
(b) between F₁ and the optical centre O of lens.

Answer 1

here is your answer ☺☺

1) at 2F1 so your image is found on 2F2
=> it's image is equal and real and inverted

2) b/w F1 and O
=> your image is found on <=some distance from 2F1


When object is placed between focus and optical centre , the image will formed beyond 2F and in that side where the image was placed. In this the image will be highly magnified and virtual and erect.
