An electron microscope is a microscope that uses a beam of accelerated
electrons as a source of illumination. As the wavelength of an electron can be up
to 100,000 times shorter than that of visible...
light microscopes allow light to pass through the specimen and use two lenses to
form an ... two lenses to form an image. Electron microscopes use beams of
electrons, rather than light, to produce images. ... No, a light microscope uses
focused light (photons) to produce a magnified image. An electron microscope
