Your microscope has 10X oculars. The diameter of the field of view measured 2.0 mm when using the 10X objective. SHOW YOUR WORK!
a. What do you calculate the diameter of the field of view to be when using the 40X objective?
b. If 20 fairly circular cells span the diameter of the field of the same microscope at 400X (total magnification), calculate the approximate size of one of these cells in microns.
