The magnification of a thin lens can be represented by the formula M = -di/do = f/(f – do)¬† where f is the focal length, di is the distance from the image to the lens, and do is the distance from the object to the lens.¬†Because the magnification is negative, the image is real and inverted.do = -di/M = 4.6 cm / -0.75 = 6.13 cm-0.75 = f/(f – 6.13) –> f = -0.75(f – 6.13) –> f(1 + 0.75) = 4.6f = 1.75/4.6 = 0.38
