Suppose an astronomical telescope is being designed to have an angular magnification of 33.2. If the focal length of the objective lens being used is 89.5 cm, find the required focal length of the eyepiece and the distance between the two lenses for a relaxed eye. Hint: For a relaxed eye, the image formed by the objective lens is at the focal point of the eyepiece. (a) Find the required focal length of the eyepiece. cm (b) Find the distance between the two lenses for a relaxed eye. cm Need Help? Submit Answer A jeweler's lens of focal length 3.5 cm is used as a magnifier. With the lens held near the eye, determine the following. (a) What is the angular magnification when the object is at the focal point of the lens? 7.14 v (b) What is the angular magnification when the image formed by the lens is at the near point of the eye (25 cm)? 8.14
