The image obtained from scanning electron microscopy (SEM) results from
A)electrons passing through the sample that reach a detector.
B)electrons that are blocked from reaching a detector through contact with sample atoms.
C)secondary electrons ejected from sample atoms through interaction with an electron beam.
D)All of these choices are correct

Question

Quizplus · Accepted Answer

The image obtained from SEM results from secondary electrons that are ejected from the sample atoms through interaction with an electron beam. These secondary electrons are then detected and used to create the image. Option A is incorrect because not all electrons passing through the sample are detected. Option B is incorrect because the electrons are not blocked from reaching the detector, but rather interact with the sample atoms to produce secondary electrons. Option D is incorrect because option A and B are not correct.
