D)Microwaves are generated when the electron beam of the SEM strikes a target.

Question

Quizplus · Accepted Answer

Microwaves are not generated by the SEM when the electron beam strikes a target. Instead, SEM uses the electron beam to generate various signals at the surface of solid specimens, including secondary electrons that produce the image. Microwaves are electromagnetic waves with much longer wavelengths than the electrons used in SEM.
