The eyepiece of a compound microscope has a focal length of 2.90 centimeter and the objective lens has f = 0.740 centimeter. An object is located 0.810 centimeter from the objective lens. Suppose a normal eye and that the final image is at infinity.
A) Find the distance between the lenses when the microscope is adjusted for a relaxed eye.
B) Compute the magnification?
