Please answer in detail with all calculations and work.

11.15. You can also make a telescope with one converging lens (the objective) and one diverging lens (the eyepiece). objective eyepiece The focal length of the convex lens is f1 and the focal length of the concave lens is f2. a. If the ray tracing works as shown, that is that parallel rays entering the objective are focused down to parallel rays leaving the eyepiece, nd the distance, d, between the two lenses. b. Compute the magnication by assuming that you are looking at a distance object which subtends an angular size 6'. Then consider a ray at angle 9 that passes through the center of the convex lens. By calculating where it passes through the concave lens, you should be able to determine its angle, 30, when it reaches the observers eye. The magnication is then 90/9. What is it in terms of the focal lengths? e. The image in this case is right-side-up. Draw a careful diagram to explain why
