How do light microscopes and electron microscopes differ from one another?

Flexi Says:
In the 1950s, scientists developed more powerful microscopes. A light microscope sends a beam of light through a specimen, or the object you are studying. A more powerful microscope, called an electron microscope, passes a beam of electrons through the specimen. Sending electrons through a cell allows us to see its smallest parts, even the parts inside the cell (Figure here). Without electron microscopes, we would not know what the inside of a cell looked like.
