What phenomenon demonstrates that electrons can exhibit wave-like behavior?.
- A.Photoelectric effect
- B.Electron diffraction
- C.Ionization
- D.Excitation
Model answer
What a good answer should say
- Electron diffraction
Explanation
Why this works
The evidence of electron diffraction shows that electrons can create interference patterns, similar to waves. This indicates that electrons possess wave-like properties, supporting the concept of wave-particle duality.
The implication is that particles, traditionally viewed as discrete entities, can also behave as waves under certain conditions. Thus, electron diffraction serves as a clear demonstration of wave-particle duality.
