You have two lenses for making a compound microscope: f_o = 0.800 cm and f_e = 1.20 cm.How far apart should you set the the lenses to get a magnification of -300? (Assume the normal near point of 25.0 cm.) A)11.5 cm B)12.7 cm C)13.5 cm D)13.9 cm E)15.0 cm

Question

The magnification of a compound microscope is given by M = -(L/f_o) * (25/f_e), where L is the distance between the lenses. Solving for L with M = -300, f_o = 0.800 cm, and f_e = 1.20 cm gives L = 13.5 cm.
