In a compound microscope, the focal length of the objective is 4.15 cm and that of the eyepiece is 7.07 cm. The distance between the lenses is 23.5 cm. (a) What is the angular magnification of the microscope if the person using it has a near point of 29.3 cm? (b) If, as normal, the first image lies just inside the focal point of the eyepiece, as in the drawing, how far is the object from the objective? (c) What is the magnification (not the angular magnification) of the objective
