A refracting telescope has a 1.27 m diameter objective lens with focal length 13.5 m and an eyepiece with focal length 3.12 cm. A.) What is the angular magnification of the telescope? B.) Describe the final image. 1. erect and virtual 2. erect and real 3. inverted and real 4. inverted and virtual 5. None of these. Two lenses are combined to form a compound lens. One of the lenses has a power 18.2 D and the other one of ?8.92 D. Find the focal length of the resulting lens. Answer in units of cm.
