Astronomers often take photographs with the objec-
tive lens or mirror of a telescope alone, without an eyepiece.
(a) Show that the image size h' for a telescope used in this
manner is given by h' fh/(f- p), where h is the object size,
f is the objective focal length, and p is the object distance.
(b) Simplify the expression in part (a) if the object distance is
much greater than the objective focal length. (c) The "wing-
span" of the International Space Station is 108.6 m, the overall
width of its solar panel configuration. When it is orbiting at an
altitude of 407 km, find the width of the image formed by a
telescope objective of focal length 4.00 m.
