Magnification occurs twice in ca microscope. It occurs the first time through
the eyepiece which magnifies the slide 10 times. Then, the objective magnifies
the slide again. This magnification depends on the number marked on the
objective. In order to calculate the total magnification the two magnifications
musty be multiplied together.
