Quizplus · Accepted Answer

The maximum magnification of a compound microscope is given by the formula M = (L * d) / (f_o * f_e), where L is the distance between the lenses, d is the least distance of distinct vision (usually 25 cm), f_o is the focal length of the objective lens, and f_e is the focal length of the eyepiece lens. Substituting the given values: M = (18 * 25) / (0.60 * 5) = 150.
