In Newton's model of light as being composed of particles, it isit's easy to imagine reflection as being the rebounding of individual corpuscles off of a surface. However, since light can also behave like a wave, it poses a challenge in visualizing reflection.
How does a wave reflect off of a surface, whether it be specular reflection or diffuse reflection? Must the wave be first absorbed, and then re-emitted? Or is there a different mechanism?
