D)All of these choices are correct

Question

Quizplus · Accepted Answer

SEM is primarily used to determine the sizes and shapes of particles comprising a sample by observing the high-resolution images of the sample's surface. While SEM can provide information about the sample's composition, this is typically done through a complementary technique like energy-dispersive X-ray spectroscopy (EDS) or wavelength-dispersive X-ray spectroscopy (WDS). SEM is also not typically used to determine the electrical conductivity of a sample.
