How does a TEM work?
A) Electrons are shot at atoms; if they collide with electrons in the atoms, a shadow is made.
B) A magnetic field moves electrons in a substance, leaving an impression.
C) Light rays are shot at the electrons, and a microscopic camera takes a photograph of the result.
D) Protons are shot at atoms; if they collide with electrons in the atoms, an shadow is made.

Question

Quizplus · Accepted Answer

Transmission Electron Microscopy (TEM) works by shooting electrons at a sample. When these electrons interact with the sample's atoms, some electrons are absorbed or scattered, creating a contrast (or "shadow") on a detector or photographic plate, which forms an image of the sample's internal structure.
