===Notes for teachers===

''These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.''

The objective here is to enable students to understand that light can be thought of as a wave or as particles.  Different models of light explain different phenomena.  It is important to get a sense of the history of how light was understood, how electromagnetism was understood and how light is the result of continuously oscillating electric and magnetic fields.
