Homework Statement
Suppose we have a microscope made out of two lenses, both with a focal length of
25mm, placed 36.5mm apart. Find how far in front of the first lens should the object be
placed to assure that the image is magnified at least by a factor of 75?
Homework Equations
The magnification for a compound microscope is : Mo x Me = (V/fo - 1) (1+ D/fe) or (-L/f1) (25/f2)
Lens formula: 1/v - 1/u = 1/f
The Attempt at a Solution
Not sure which equation to use as the first one doesn't make use of the distance btw the two lenses. And still not sure how Ill get the position of object from the first lens.
