Image obtained is always virtual. Therefore, the Newton's lens formula is: 2 1 x 2 f s (8) where f s is the equivalent focal length of the two-lens system and this focal length can The two are kept at 15 cm apart from each other. 2 nd Sem, A.Y. Choose a converging lens for the experiment. Set the distance between the cross-threads and lens to a measured value (object distance) greater than the approximate focal length and aim the lens at the screen. Based on Loyd #41.
