A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...
