There are three models of light that students in physics learn. This article explains each of them and provides great diagrams to understand how they behave. Imbedded in the article are some simple activities that will help to understand the different models. As the author points out, other phenomena of science also have more than one model to explain it. This article seemed to appear in an issue about models and fits in well with this theme. There is a great deal to learn and understand but material is presented very clearly.
