Calculating Magnification


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.


  objective lens eyepiece total magnification

Medium Power 10x 10x 100x
High Power 40x 10x 400x
