Can viruses be seen with microscope
WebThis means that electron microscopes can be used to visualise viruses, molecules and even individual atoms. The wavelength of electron movement is measured in picometres (billionths of a millimetre), so … WebThere are two major types of electron microscopy. In scanning electron microscopy ( SEM ), a beam of electrons moves back and forth across the surface of a cell or tissue, creating a detailed image of the 3D surface. This type of microscopy was used to take the image of the Salmonella bacteria shown at right, above.
