    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...

    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?

    9. A simple telescope can be constructed from two convex lenses. Consider a telescope that uses a 500 mm lens (focal length of 500 mm) for the objective lens and a 150 mm lens for the eye piece. 1. How far apart must the lenses be placed to view an object that is 100 m away (from the objective lens) and appears to be 20 cm in front of the eyepiece lens? 2. What magnification does the telescope produce for...

    6. A telescope is an afocal system composed of an Objective (positive lens or mirror) and an Ocular ( positive or negative lens or mirror). Calculate the transverse angular magnification of a Galilean Telescope focused at infinity if the Objective is a positive lens of 0.75 diopter (fob=+ 1350mm) and the Ocular is a negative lens of -6.6 diopter (foc= -152mm). Consider the Objective and the Ocular as thin lenses. Attache the ray diagram that supports your solution.
