An old refracting telescope in a museum is 44.0 cm long and the caption states that the telescope magnifies images by a factor of 29.0. Assuming these numbers are for viewing an object an infinite distance away with minimum eyestrain, what is the focal length of each of the two lenses?
For this I have done fo/fe = 29 and fo+fe = 44
29fe = 44
(29)(1.6) = 46.4
But both these answers are wrong. Why? I cannot figure this out for the life of me. Please help.
