Best ResponseYou've already chosen the best response.0this is what i got Scanning electron microscopes (SEM) are useful for studying the details of a specimen’s surface. The electron beam scans the specimen’s surface, which is coated with a thin layer of gold metal. The electrons that scatter off of the goldcoated surface are focused onto a screen, forming a detailed image of the specimen surface. The image is threedimensional and black and white.
