what do scanning electron microscopes and transmission electron microscopes have in common?\nboth generate three - dimensional images.\nboth offer magnification to the atomic level.\nboth are used to view the parts of a cell.\nboth require a vacuum.
Answer
Brief Explanations:
Scanning electron microscopes (SEM) and transmission electron microscopes (TEM) work by using a beam of electrons. Electrons are easily scattered by air molecules, so both require a vacuum - filled chamber to operate properly. SEM generates 3 - D like images while TEM gives 2 - D images. TEM can offer magnification to atomic level better than SEM in some cases. SEM is often used for surface imaging and TEM for internal structure of cells and materials. But the key commonality here is the vacuum requirement.
Answer:
Both require a vacuum.
