The medium-power objective lens in a laboratory microscope has a focal length f objective = 4.00 mm. (a) If this lens produces a lateral magnification of –40.0, what is its “working distance”; that is, what is the distance from the object to the objective lens? (b) What is the focal length of an eyepiece lens that will provide an overall magnification of 125?
