Figure $$\PageIndex{1}$$: In this image of pollen taken with an electron microscope, the bean-shaped grains are about 50μm50μm long. Electron microscopes can have a much higher resolving power than a conventional light microscope because electron wavelengths can be 100,000 times shorter than the wavelengths of visible-light photons.
