What is the angular magnification of the telescope

Reference no: EM13656281

An amateur astronomer decides to build a telescope from a discarded pair of eyeglasses. One of the lenses has a refractive power of 11 diopters, while the other has a refractive power of 1.1 diopters. (a) How far apart should the lenses be separated? (b) What is the angular magnification of the telescope?
