(a) What magnification is produced by a 0.150 cm focal length microscope objective that is 0.175 cm from the object being viewed?
(b) What is the overall magnification if an eyepiece that produces a magnification of 7.90x is used?
(c) Jupiter subtends an angle of 1.67 x 10-4 rad when viewed by the unaided eye and 3.25 x 10-2 rad when viewed through an astronomical telescope that has a 0.035-m focal length eyepiece. Determine the focal length of the telescope's objective lens.
