EXPERIMENT TO MEASURE THE FOCAL LENGTH OF A CONVERGING LENS

In this video, we obtain the focal length of a converging lens using a raybox, a screen, object (thin metallic threads inside the raybox) and a metre rule. By varying the object distance, the magnification of the image was obtained. The estimated variation in magnification was plotted against the variation in object distance. From the graph, the focal length of the lens was obtained.
My sincere apologies for any abrupt change in the audio quality at some point in the video. Hopefully, it doesn't reduce the value of the information disseminated in this video.
