An object at a certain height in the positive y axis is placed at a distance D from a screen. We see that a thin lens can form a real image of the object onto the screen when it is placed at two different positions between the screen and the object. These two positions are separated by a distance d.
a) Give the ratios h1/h2 between the heights h1 and h2 of the two images on the screen, as a function of D and d.
b) the height of the object as a function of h1 and h2
c) the focal length f of the lens
d) the minimum possible value of D as a function of f
