Try this first
In which scenario would the corpuscular theory of light be more applicable than the wave theory?.
- A.When explaining the photoelectric effect.
- B.When discussing light's speed in a vacuum.
- C.When analyzing diffraction patterns.
- D.When describing the bending of light at a prism.
Model answer
What a good answer should say
- When explaining the photoelectric effect.
Explanation
Why this works
The corpuscular theory is more applicable when explaining the photoelectric effect, as it accounts for the emission of electrons from materials when exposed to light, which requires the concept of light as discrete packets of energy (photons). In contrast, wave theory does not adequately explain this phenomenon.
Thus, the choice of model depends on the experimental context.
