When using microscopes, two variables matter the most: magnification and resolution.

Magnification
- Magnification is a measure of how much larger the image is than the object itself.
- We can use a microscope to magnify things.
- The image of an object seen through a microscope will appear larger than the real thing.
- For example, the image from the microscope is 5 times larger than the real object, so the magnification is 5×.
Resolution
- Resolution is the ability to tell apart two or more objects that are close together.
- The higher the resolution of an image, the better the quality of the image is.
