Question

__________________ is a electron microscope which scans the surface of sample to form an image.

• A. Electron probing
• B. TEM
• C. SEM
• D. All of the above

Answer 1

The correct option is C SEM

In a scanning electron microscope or SEM, a beam of electrons scans the surface of a sample. The electrons interact with the material in a way that triggers the emission of secondary electrons. These secondary electrons are captured by a detector, which forms an image of the surface of the sample. Therefore, the correct answer is option C.
