a] Magnification of the telescope = focal length of the objective / focal length of eyepiece = fo/fe
here, the objective is the mirror and so, fo = 80 m
focal length of eyepiece = 50 mm = 0.05 m
therefore, magnification = 80/0.05 = 1600
b] From the relation above for magnification, the focal length of the eyepiece must be made small in order to make the denominator smaller so that the magnification is larger.

A small object is located 28.0 cm in front of a concave mirror with a radius of curvature of 38.0 cm. Where will the image be formed? (Enter a negative value if the image forms behind the mirror.) An object with a height of 42 cm is placed 1.9 m in front of a convex mirror with a focal length of -0.49 m. Find the location and magnification of the image produced...
