Detailed explanation-1: -The scanning electron microscope (SEM) lets us see the surface of three-dimensional objects in high resolution. It works by scanning the surface of an object with a focused beam of electrons and detecting electrons that are reflected from and knocked off the sample surface.
Detailed explanation-2: -A scanning electron microscope (SEM) directly produces an image of the three-dimensional structure of the surface of a specimen.
Detailed explanation-3: -The dissecting microscope provides a lower magnification than the compound microscope, but produces a three-dimensional image. This makes the dissecting microscope good for viewing objects that are larger than a few cells but too small to see in detail with the human eye.
Detailed explanation-4: -Scanning electron microscope is used for obtaining 3 dimensional and surface images.
Detailed explanation-5: -Answer and Explanation: The type of electron microscopy that gives three-dimensional images of a surface is B) scanning electron microscopy (SEM). Like transmission electron microscopes, SEMs use electron beams to visualize specimens; however, SEMs produce three-dimensional images of the specimens.
