A student uses a microscope to view a red blood cell. The
objective lens has a focal length of 0.85 cm. The eyepiece
has a focal length of 2.9 cm. Suppose the red blood cell is
1.0 cm from the objective lens. The objective lens and
eyepiece are separated by L = 8.50 cm.
Where is the final image relative to the eyepiece? Is it
to the right or to the left of the eyepiece? Is the final
image real or virtual?
