What is Focal Length of Convex Lens Experiment about?

This experiment aimed to find the focal length of a convex lens using two graphical methods. Observations were made by varying the position of a lens between two needles and measuring the object and image distances. Graphs were plotted of 1/u vs 1/v and u vs v, from which the focal length was determined to be 20 cm both times. Sources of error included parallax and non-vertical uprights, while precautions involved removing parallax and ensuring tight screws and vertical needles.
