You have lenses with focal lengths f₁ = 4.0 cm and f₂ = 12 cm. Assume your near-point distance is 25 cm and consider the following configurations of these lenses. 

(a) For magnifying glasses, what magnification could you achieve with each lens? 

(b) What is the maximum magnification you could achieve if you used these lenses in a compound microscope of length 25 cm? 

(c) What maximum magnification could you achieve if you made them into a telescope? What is the separation distance between the lenses for the telescope configuration?
