Reflection Wave or Particle

Activity Overview

The duality model for light has been argued for many years, is it particle or wave, perhaps both. This activity looks at reflection and whether the particle or wave concepts models light best. Students watch the animation of a wave and then a particle on a wave as they strike a surface and it gets reflected. The location of the image is shown for students to consider. An option is also included to show the position of an observer.

What model is best for the reflection of light: Wave or Particle? Watch the animations, reveal the observer and consider the point and wave models illustrated in this activity. Does this activity help you understand the wave/particle duality model for light?
