| electron wavelength | About 100,000 times shorter than those of visible light. |
| micrograph | A photograph of an image formed with a microscope. |
| scanning tunneling microsope | A computer analyzles a tunnel formed in electron orbitals, this produced between the tip of a needlelike probe and an atom. |
| transmission electron microscpe | Electrons pass through a thin section of cells to form and image. |
| wavelength | The distances from one wave's peak ro the peak of the wave behind it. |
| compoud light microscope | Glass lenses bend incoming light rays to form and enlarged image of a cell or some other specimen. |
| scanning electron microsope | A narrow beam of electrons moves back and forth across the surface of a specimen coated with a thin metal layer. |
