The objective lens of an astronomical telescope forms an image of a
distant object at the focal point of the eyepiece, which has a
focal length of 7.2 cm. If the two lenses are44.3 cm apart, what is
the angular magnification?
Homework Answers
L = fo + fe = 44.3
fe = 7.2 cm
fo = 44.3-7.2
fo = 37.1 cm
angular magnification m = fo/fe = 37.1/7.2 = 5.15

Galileo's Telescope Galileo's first telescope used a convex objective lens with a focal length f=1.7m and a concave eyepiece, as shown in the figure. (Figure 1)When this telescope is focused on an infinitely distant object, and produces an infinitely distant image, its angular magnification is +3.0. A. What is the focal length of the eyepiece? in cm b. How far apart are the two lenses?

A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...

please make sure you have the right answer. You are given two converging lenses that have focal lengths of 63 mm and 26 mm. (a) Show how the lenses should be arranged to form a compound microscope that has a tube length of 157 mm. State which lens to use as the objective, which lens to use as the eyepiece. Use the 26 mm focal length lens as the eyepiece and the 63 mm focal length lens as the objective....
