The magnifying power of a telescope is the ratio of an object's angular diameter to its
naked eye diameter. This depends on the focal length of both lenses.
Magnification = focal length of objective lens / focal length of eyepiece lens
A small refracting telescope has an objective of focal length 100 cm. If the eyepiece
has a focal length of 4.0 cm, what is the magnification of the telescope?
A) 0.25 cm
B) 25 cm
