QuestionWhat we see with this microscope?

QuestionCan the microscope see a virus?
HannahCommunity AnswerNo, because the majority of viruses are too small for that. You would need an electron microscope to view them. There are a few so called "giant viruses" (200-400 nm) that could be observed through an optical (light) microscope, but not without laboratory equipment.
