Answer:
Explanation:
Electron Microscope
Scanning Electron Microscope (SEM)
In scanning electron microscopy, the beam of electrons is scanned across the surface of a sample in a raster pattern. The image is formed by secondary electrons emitted from the surface when they are excited by the electron beam.
Answer:
electron microscope
Explanation:
In scanning electron microscopy is a type of microscpe, the beam of electrons is scanned across the surface of a sample in a raster pattern. The image is formed by secondary electrons emitted from the surface when they are excited by the electron beam. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail. There are two types of electron microscope, namely; Transmission electron microscope and Scanning electron microscope. Unlike the TEM, where the electrons in the primary beam are transmitted through the sample, the Scanning Electron Microscope (SEM) produces images by detecting secondary electrons which are emitted from the surface due to excitation by the primary electron beam.
