Problem

A teaching microscope has a tube length L=180L = 180 mm, measured from the focal point of the objective to the focal point of the eyepiece. The objective has focal length fo=6.0f_o = 6.0 mm and the eyepiece fe=20f_e = 20 mm. The specimen sits just outside the objective's front focal point and the eyepiece is used relaxed, with the standard near point d0=250d_0 = 250 mm. What is the overall magnification MM, sign included?
