You probably observed biological specimens through a microscope in your science lab back in high school.If youโve never seen what kinds of images microscopes produce.all microscopes produce black-and-white images? If yes, whatโs the reason behind that?
๐color is a property of light (i.e., photons), and since electron microscopes use an electron beam to image a specimen, thereโs no color information recorded. The area where electrons pass through the specimen appears white, and the area where electrons donโt pass through appears black.
