Show your solution. Twelve (14) ocular divisions coincide with three stage divisions. Assuming that the graduations of the stage micrometer are spaced 10 um, what is the known distance between the three stage divisions in millimeters? Show your solution. c) With the same given information on b), what would be the distance of one ocular division?
