Electron Microscopes (EMs) are scientific instruments that use a ray of electrons to examine small matter on a very fine scale. They are extremely useful, as they can produce the following information;
*Topography; this is how the surface appears, for example the texture.
*Morphology; this is the shape and size of the particles that make up the matter.
*Composition; this is the elements and the compounds the matter is composed of.
*Crystallographic Information; this is how the atoms are arranged in the matter.
