Question

Write the experimental procedure of the experiment to find the focal length of a convex lens using the distance of the object (u) and distance of the image (v).​

Answer 1

Answer:

If you know the distance of the object you're magnifying from the lens and the focal length of the lens, finding the distance of the image is easy with the lens equation. The lens equation is 1/f = 1/do + 1/di, where f = the focal length of the lens.
