Science 101: Why are there so many different models of light?

by: William C. Robertson, Ph.D.

Is light a ray, a wave, or a particle? Yes, yes, and yes. An article in this issue (“The Benefits of Scientific Modeling,” p. 40) discusses the process of scientific modeling, and light is a great example of how modeling works. There are three viable models for light, each appropriate for different situations. The author will discuss the situations to which each applies, and then discuss how these different explanations are all compatible with one another.
