- Traveling in a straight path
- Photoelectric effect

Reason: The photoelectric effect requires quantized photons (particle behavior). Rectilinear (straight‑line) propagation is a corpuscular prediction (particles travel in straight lines); phenomena like interference and bending around objects (diffraction) require the wave model, and reflection can be explained by either model.
