Why do "shadows" result in TEM images?
A) Light does not pass through the atoms, resulting in shadows.
B) Electrons are stopped by atoms, resulting in shadows.
C) There are no objects for the electrons to hit, which results in shadows.
D) Electrons pass through the atoms, resulting in shadows.

Question

Quizplus · Accepted Answer

TEM (Transmission Electron Microscope) uses a beam of electrons to scan the sample. These electrons are scattered or absorbed by the atoms in the sample, and the resulting pattern is used to create an image. When electrons are stopped by the atoms, they do not reach the detector, resulting in "shadows" in the image.
