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.

Videos on Nature of Light The following videos are useful in understanding the nature of light.

 * 2) What is Light
 * 3) Thomas Young's Double Slit Experiment

Activity No # 1 - Simulation of double slit experiment
The objective of this activity is to demonstrate an important experiment from the 18th century that made physicists rethink about the nature of light.   Launch the simulation from the PhET website or download it and run. Discuss the simulation with the following questions.
 * Estimated Time
 * Materials/ Resources needed
 * Prerequisites/Instructions, if any
 * Multimedia resources
 * Website interactives/ links/ simulations
 * Process (How to do the activity)
 * Developmental Questions (What discussion questions)
 * Evaluation (Questions for assessment of the child)
 * Question Corner
