Question: A refracting telescope, like a compound microscope, contains two converging lenses, the objective lens and the eyepiece lens, positioned on a common optical axis (Figure

A refracting telescope, like a compound microscope, contains two converging lenses, the objective lens and the eyepiece lens, positioned on a common optical axis (Figure 33.49). However, a telescope is designed to view large, very distant objects, whereas a microscope is used to view very small objects that are placed very close to the objective lens. Consequently, the arrangement of lenses in a telescope is different from the arrangement in a microscope. The telescope's objective lens is positioned to form a real image of very distant objects, and the eyepiece lens is positioned to form a virtual image of the image produced by the objective lens, to be viewed by an observer.

(a) How should the lenses be arranged to accomplish this?

$(b)$ What is the overall magnification produced by the telescope?
