A microscope has an eyepiece of focal length 2.10 cm and an objective of focal length 4.10 cm. The eyepiece produces a virtual image at the viewer's near point (25.0 cm from the eye).
a. How far from the eyepiece is the image formed by the objective?
b. If the lenses are 22.6 cm apart, what is the distance from the objective lens to the object being viewed?
c. What is the angular magnification?
