The "tube length" of a microscope is defined to be the difference between the (objective) image distance and objective focal length: L=di%u2212fobjective. Many microscopes are standardized to a tube length of L = 160mm . Consider such a microscope whose objective lens has a focal length fobjective = 7.49mm .

a) How far from the object should this lens be placed?

b) What focal length eyepiece would give an overall magnification of -53?

c) What focal length eyepiece would give an overall magnification of -100?
