ou wish to purchase a telescope that is easy to transport from one location to another. You finally decide on one with a barrel length (distance between objective lens and eyepiece) of 1.39 m and an ‘angular magnification’ of −75.9. For telescopes the angular magnification is defined as -fo/fe, where fo = objective lens focal length and fe = eyepiece focal length. Assume that the final image is very far away from the observer as they keep the eye most relaxed while observing. Determine the following. (a) the focal length of the objective lens
