Wave-Particle Duality

In this topic, you will learn about the dual nature of light. Light has particle properties and wave properties. These properties were theorized because classical physics could not explain the results of new experiments; therefore, new theories were developed to offer explanations for these observations. These revolutionary ideas changed physics.

Essential Questions:

• What is the dual nature of light? 
• What is a photon? 
• What important experiments showed physicists that classical physics was inadequate?
