C)scanning electron microscope (SEM).
D)confocal microscope.

Question

Quizplus · Accepted Answer

The scanning electron microscope (SEM) produces images by scanning a beam of electrons over the surface of a specimen, which generates secondary electrons that are detected and used to form an image. This technique produces high-resolution three-dimensional images of surfaces with great detail. The brightfield light microscope produces images by passing light through a sample, while the transmission electron microscope (TEM) uses a beam of electrons transmitted through a thin sample. The confocal microscope uses a laser to create optical sections of samples.
