Exam-style question
Try this first
Explain when diffraction and the photoelectric effect are observed in experiments. Which phenomenon is more suitable for demonstrating the wave nature of light?.
Model answer
What a good answer should say
- Diffraction is observed when light passes through narrow slits or around edges, producing interference patterns, which clearly demonstrate wave behavior.
- The photoelectric effect is observed when light shines on certain metals, causing electron emission.
- Diffraction is more suitable for demonstrating the wave nature of light due to the clear interference patterns it produces.
Explanation
Why this works
This question assesses the ability to apply knowledge of diffraction and the photoelectric effect to experimental contexts. By explaining when each phenomenon is observed and concluding which is more suitable for demonstrating wave nature, students show their understanding of the practical implications of wave-particle duality.
