Instruction: Conduct research regarding the properties of light and use it to evaluate the claims. Your evidences should be based on known experiments such as photoelectric effect, pair production (particle), reflection, refraction, diffraction, interference (wave).

 

Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other. [Clarification Statement: Emphasis is on how the experimental evidence supports the claim and how a theory is generally modified in light of new evidence. Examples of a phenomenon could include resonance, interference, diffraction, and photoelectric effect.] [Assessment Boundary: Assessment does not include using quantum theory.]
