Answer:
Compound microscopes can magnify specimens enough so that the user can see cells, bacteria, algae, and protozoa. You cannot see viruses, molecules, or atoms using a compound microscope because they are too small; an electron microscope is necessary to image such things.
A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially, a compound microscope consists of structural and optical components.
