Why is electron diffraction considered strong evidence for wave-particle duality?.
- A.It shows that electrons can be ionized.
- B.It demonstrates the particle nature of light.
- C.It reveals that electrons can interfere like waves.
- D.It indicates that electrons have a fixed position.
Model answer
What a good answer should say
- It reveals that electrons can interfere like waves.
Explanation
Why this works
The evidence from electron diffraction shows that electrons create interference patterns, which is a hallmark of wave behavior. This observation implies that electrons cannot be fully described as particles alone, supporting the concept of wave-particle duality.
Consequently, electron diffraction is a pivotal demonstration of how quantum objects can exhibit both wave and particle characteristics.
