- Reflection is a kind of property
- Reflection is when particles bounce off a surface
- Reflection is when a wave bounces off a surface and travels in the opposite direction relative to the angle of incidence
- So, both particles and waves have the property of reflection

- Both particles and waves have the property of reflection
- Reflection is a property of light
- Therefore, light can be seen as both particles and waves

Hence, light can be seen as both particles and waves
Question: Light sometimes behaves as waves and other times as particles. Which property of light is equally explainable by treating light as either particles or waves?
