Which choices are correct explanations about the scanning electron microscope (SEM)? (Select all that apply.) Useful resolution range for SEM is much narrower than the optical microscopes. SEM can investigate non conductive samples as good as the conductive ones. Samples for SEM do not need to be polished nor etched. Electron beam is the main light source for SEM. The condensed beam needs to pass through the specimen to obtain the picture for SEM.
