Microscope and magnification

Elements: 

The light microscope was invented about 350 years ago. it uses light to form magnified images of cells and other tiny objects. The best light microscope can produce of about 20000 times: x2000. The electron microscope was invented in the last century. It uses electrons to produce magnifications of up to 2 million times. The higher magnification and resolving power of electron microscopes allow scientists to see and understand sub-celluar structures.

Resolving Power:

A microscope with a high resolution allows you to distinguish between two obejcts that are very close together.
