Question:
A luminous object and a screen are a fixed distance D apart.
(a) Show that a converging lens of focal length f, placed between object and screen, will form a real image on the screen for two lens positions that are separated by a distance d = √D(D - 4f).
(b) Show that (D – d/D + d)2 gives the ratio of the two image sizes for these two positions of the lens.
