Question

Exercise 34.63 < 11 of 12 > Constants A reflecting telescope (see the figure labeled (a) (Figure 1)) is to be made by using a spherical mirror with a radius of curvature of 1.24 m and an eyepiece with a focal length of 1.90 cm. The final image is at infinity Part A What should the distance between the eyepiece and the mirror vertex be if the object is taken to be at infinity? 90 AED ROE?

Answer 1

Soln: fei object and image hs beth at inpinity,f fe equals the ditarka d between the eyepiece and the mirset vertex Radius of cusvature of phesical mitio R=124 m 1t focal tength is 2 0.62m focat length of iece te 190 cm 0.019m Part A- Calculate the distance blus the eyopiece and the minos taron at infinity Vestex if the object =O.62m + 0.019 mn d O639 m Part B Caleulale the angulat magnification f fe 1 mI 0.62m ubio-0 1MI 32 63
