Lesson 5 of 9
Using a microscope
Goal: Use a light microscope and calculate total magnification.
A microscope makes tiny things look much bigger.
Total magnification = eyepiece lens × objective lens
- Example: a ×10 eyepiece with a ×40 objective gives 10 × 40 = ×400.
- Start on the lowest power lens. It is the easiest to focus.
- Coarse focus first, then fine focus to sharpen.
