Answer 1

Answer:

Experiment with lens:-

Now move the screen until you get a sharp, diminished & inverted image of the distant object. Mark the point on the scale where you get the desired image. The difference between the lens mark & the screen mark will give the focal length. Now place the lens on a new position that is 10 cm and find the focal length.
