|---|
| base | supports the microscope |
| arm | supports the body tube |
| low power objective | magnifies objects 4X |
| fine adjustment knob | focuses the object under low and high power |
| coarse adjustment knob | focuses the object under low power only |
| eyepiece | where you look through; multiples 10X |
| high-power objective | magnifies objects 40X |
| The power of the eye piece is | 10X |
| If the objective lens has a power of 4, what is the total magnification? | 10 X 4 = 40 |
| If the power of the objective lens is 10, what is the total magnification? | 10 X 10 = 100 |
| If the power of the objective lens is 40, what is the total magnification? | 10 X 40 = 400 |
| Power of the eyepiece X power of the objective lens = | total magnification |
