Magnification and calibration

Magnification = Size of image / Acutal size of object

Magnification is how many times larger the image is than the actual size of the object being viewed

Interchangeable  obkective lenses on a compound light microscope allow a user to adjust the magnification.

The resolution of a microscope  determines the amount of detail that can be seen.

The higher the resolution the more details are visible

Diffraction is the tendency of light waves  to spread as they pass close to physical structures.
