Experiment 3 The Simple Magnifier, Microscope
... Experiments 1 and 2 dealt primarily with the measurement of the focal lengths of simple lenses and spherical mirrors. The question of lateral magnification, given by |m| = s0 /s = i/o, follows logically. In some cases (typically with telescopes) the object distance is functionally infinite, at which ...
