Electron Diffraction Flashcards
1
Q
What kind of wire do you need for electron diffraction?
A
High resistance, so current causes thermionic emission of electrons
2
Q
What are the electrons accelerated through?
A
A high potential difference
3
Q
What acts as the obstacles for diffraction?
A
Graphite atoms
4
Q
Why is electron diffraction done in a vacuum?
A
To remove interactions with air
