Quizplus · Accepted Answer

The magnification of a compound microscope is given by the formula: Magnification = (L / f_o) * (25 / f_e), where L is the tube length (20 cm), f_o is the focal length of the objective (0.90 cm), and f_e is the focal length of the eyepiece (3.6 cm). Substituting the values, we get Magnification = (20 / 0.90) * (25 / 3.6) ≈ 150.
