A microscope with an overall magnification of 750 has an objective that magnifies by 190. (a) What is the magnification of the eyepiece? (b) If there are two other objectives that can be used, having magnifications of 100 and 400, what other total magnifications are possible? (objective = 100x) (objective = 400x)
