Scanning electron and transmission electron microscope

Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.

E

Expert

Verified

The SEM or scanning electron microscope has become more admired than the TEM or transmission electron microscope as it can generate images of high resolution, better clarity and three dimensional qualities and needs less sample preparation.
