The eyepiece of a compound microscope has a focal length of 2.90 cm , and the objective lens has f = 0.720 cm . An object is placed 0.810 cm from the objective lens. Assume a normal eye and that the final image is at infinity.

a)Calculate the distance between the lenses when the microscope is adjusted for a relaxed eye.

Express your answer to two significant figures and include the appropriate units.

b)Calculate the total magnification.

Express your answer using two significant figures.

part A is NOT .15 cm, 3.05 cm, 13.8, or 3.1 cm.
