Teaching Outlines

Concept #1 - Dual nature of light

Learning objectives

  1. It is possible to look at light and other electro magnetic radiation as a wave or as a particle known as the photon.
  2. Light travels as electromagnetic radiation; with waves of different wavelengths
  3. Light interacts with material particles in discrete packets called photons
  4. Different wavelengths are associated with photons of different energies

Notes for teachers

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.

The following videos are useful in understanding the nature of light.
