8. If you have lenses with the following focal lengths: f = 5.00 cm, f = 10.0 cm, f = -5.00 cm, f = -10.0 cm and f = 200. cm, then which pair of lenses would create the maximum magnification (a) for a compound microscope, and (b) for a diffracting telescope. Explain. And if only one lens was used for eyeglasses, then (c) which lenses would be used by a person with hyperopia, (d) and used for a person with myopia? Explain.
