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 of the image formed by the eyepiece lens
(b) Determine the distance, in centimeters, of this image from the eyepiece
(c) Determine the size, in terms of object height, H, of this image

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?

An objective lens has a focal length of 1.5 cm and the object is positioned 1.7 cm(do) from the objective lens, what is the distance between the objective lens and the image (di) produced by the objective lens? What is the magnification produced by the objective lens? The real image formed by the objective lens then becomes the "object" for the eyepiece lens. If the objective and eyepiece lenses are 15.0 cm apart, what is the distance between the "object"...
