Exam-style question
Try this first
In which scenario would a wave model of light be more applicable than a particle model?.
- A.When observing the photoelectric effect.
- B.When analyzing diffraction patterns.
- C.When measuring the energy of photons.
- D.When calculating the momentum of photons.
Model answer
What a good answer should say
- When analyzing diffraction patterns.
Explanation
Why this works
Diffraction patterns are best explained by the wave model of light, as they demonstrate the interference of waves, which cannot be accounted for by a purely particle model.
