Question | Answer |
ocular lens | lens at the top that you look through; usually has a magnification power of 10x |
body tube | connects eyepiece to revolving nosepiece |
course adjustment knob | larger knob; moves body tube to produce larger changes in focus |
fine adjustment knob | smaller knob; moves body tube to produce small changes in focus and see details more clearly |
arm | supports the body tube and connects it to the base |
revolving nosepiece | holds 2 or more objective lenses and can be rotated to easily change level of magnification |
objective lenses | lenses attached to revolving nosepiece |
stage clips | hold the slide in place on the stage |
diaphragm | controls the amount of light allowed to pass through specimen |
base | bottom of microscope that supports all of its parts |
how you should carry a microscope | 2 hands - one on arm, one under base |
field of vision | area of the slide you see when you look through the microscope |
longest objective lens | highest power of magnification |
how to find total magnification | ocular lens x objective lens |
how increased magnification affects field of vision | as magnification increases, field of vision decreases |
ocular lens = x10, objective lens = x40
What is the total magnification? | x400 |
