Question

FAN AND MEDAL!
what is the scanning electron microscope most useful or viewing?

Answer 1

the scanning electron microscope (SEM) uses a focused beam of high-energy electrons to generate a variety of signals at the surface of solid specimens. The signals that derive from electron-sample interactions reveal information about the sample including external morphology (texture), chemical composition, and crystalline structure and orientation of materials making up the sample

Answer 2

yea but what is it most useful for viewing? like the compound light microscope is most useful for viewing small objects that are not visible to the naked eye.

Answer 3

The most common mode of detection is by secondary electrons emitted by atoms excited by the electron beam

Answer 4

so it is most useful to view secondary electrons emitted by atoms excited by the electron beam?

Answer 5

yep
