A projection lantern is used to give the image of a slide on a screen. If the image is 24 times as large as the slide and the screen is 72.0m from the projecting lens, what is the position of the slide from the lens?
V = 72m
U = ?, Magnification = 24
But Magnification = V/U
∴ 24 = 72/U
U = 72/24
U = 3.0m
There is an explanation video available below.
