A compound microscope has an objective lens of focal length 15.0 mm and an eyepiece that gives an angular magnification of 5.00 for a final image at infinity. The tube length of the microscope (taken here to be the distance between the objective and eyepiece lenses) is 16.0 cm. Assume the near point to be at 25 cm.
(a) How far from the objective lens should the object be placed?
(b) What is the magnification due to the objective lens alone?
(c) What is the total magnification of the microscope?
