The image serves as a virtual object for the eyepiece. The final image is virtual and erect. (a) Prove that the angular magnification is (b) A Galilean telescope is to be constructed with the same objective lens as in Exercise 34.65. What focal length should the eyepiece have if this telescope is to have the same magnitude of angular magnification as the one in Exercise 34.65? (c) Compare the lengths of the telescopes.
