Question

While performing the experiment on the determination of focal length of a convex lens, four student obtained the image of the same distant tree on the screen:



Which diagram shows the formation of image correctly?
(1) A
(2) B
(3) C
(4) D

Answer 1

When the rays coming from a distant object are converged through a convex lens to form an image on its focus, the image formed at focus is real and inverted in nature. So, the image of a distant tree would be inverted if focussed through a convex lens to form a clear image on a screen placed at the focal point of the lens.

Hence, the correct answer is option 4.
