When accelerated electrons passed through a crystal lattice, they interacted with the small gaps between atoms and formed a diffraction pattern like the one ...

Electron diffraction is used to study matter by firing electrons at a sample and observing the resulting interference pattern.

Explain electron diffraction as evidence for the wave nature of particles like electrons. •. Explain that electrons travelling through polycrystalline graphite ...

The electron diffraction pattern has a bright central disc, and circular bands around it. As the electron speed increases, the pattern gets tighter.
