What is electron diffraction and how does it provide evidence for wave-particle duality?.
Model answer
What a good answer should say
- Electron diffraction occurs when a beam of electrons passes through a narrow slit or around an obstacle, creating an interference pattern.
- This pattern indicates that electrons exhibit wave-like behavior, as particles would not produce such patterns.
- The implication is that electrons cannot be described solely as particles, supporting the concept of wave-particle duality.
Explanation
Why this works
This answer effectively explains the phenomenon of electron diffraction and its significance in demonstrating wave-particle duality. It tests the understanding of how quantum mechanics challenges classical physics concepts.
