Which of the following best explains why electron diffraction supports wave-particle duality?.
- A.Electrons can only exist in discrete energy levels.
- B.Electrons can create interference patterns.
- C.Electrons have a defined mass and charge.
- D.Electrons are emitted from metals when exposed to light.
Model answer
What a good answer should say
- Electrons can create interference patterns.
Explanation
Why this works
The evidence that electrons create interference patterns when diffracted indicates that they exhibit wave-like behavior. This behavior contradicts classical particle descriptions, implying that electrons possess both particle and wave characteristics.
Therefore, the ability of electrons to create interference patterns is a fundamental aspect of wave-particle duality.
