An object (bold arrow) is located at a distance of 3 *f* / 2 (i.e. at x = 3 *f* / 2) in front of a diverging lens as shown in the figure. Note that *f* is positive, so the focal length of this lens is - *f*.

Suppose the object is now placed at x = - *f*. What is the magnification M?

a) M = 0

b) M = 1/2

c) M = 1
