==Concept #1 - Dual nature of light==
==Concept #1 - White Light is made up of colours==
===Learning objectives===
#White Light is made up of seven constituent colours
#Introduction to the corpuscular theory of light
===Notes for teachers===
Reinforce the learning from activity on [http://karnatakaeducation.org.in/KOER/en/index.php/Light#Activity_No_.23_1B_-_Recombination_of_Colours Recombination of Colours]. Also understand the model as proposed by Newton on the nature of light and examine the limitations of this theory.
===Activity No # 1A - Using a prism to split and combine white light ===

* '''Estimated Time''' - 2 periods of 40 minutes
* '''Materials/ Resources needed'''
White paper, Pins, Source of Light, Prisms, Dark room
* '''Prerequisites/Instructions, if any'''
#Activity on [http://karnatakaeducation.org.in/KOER/en/index.php/Light#Activity_No_.23_1B_-_Recombination_of_Colours Recombination of Colours]

{{#ev:youtube| uucYGK_Ymp0| 150| left}} - Newton's Prism Experiment. This is a demonstration of the experiment showing the splitting and recombination of white light. Useful to show the students after the demonstration/ experimentation in class.
* '''Process (How to do the activity)'''
#Demonstrate the dispersion using a prism and recombination of the light
#Students must do this experiment in groups
#The teacher must demonstrate carefully how to position the prism, how to observe rays in light experiments
#students must be able to draw ray diagrams showing the split of the spectrum
* '''Developmental Questions (What discussion questions)'''
#When the light falls on the prism, what did you expect to see? What happened?
#What are the colours you see? What is the order of the colours?
* '''Evaluation (Questions for assessment of the child)'''
#From the incoming beam of light, which colour showed the maximum angle of dispersion? (This question can be picked up later to discuss wavelengths and electromagnetic spectrum)
#If you change the direction of the incoming light, what happens to the dispersion?
#Observe the accuracy of the diagrams
* '''Question Corner'''

The objective is to study Newton's theory on light
* '''Estimated Time''' - 30 minutes
* '''Materials/ Resources needed'''
Computer, projector, power
* '''Prerequisites/Instructions, if any'''
* '''Multimedia resources'''
{{#widget:YouTube|id=uO2uyvf-E3k}}
* '''Website interactives/ links/ simulations'''
* '''Process (How to do the activity)'''
Watch the video and discuss with the student their understanding.
* '''Developmental Questions (What discussion questions)'''
#Can reflection and refraction be explained using this? How?
#Newton said that different colours can be caused by different sizes of particles. Knowing what you know of the eye, explain how this would have worked.
#What do you not understand about this theory based on your observations?
* '''Evaluation (Questions for assessment of the child)'''
Draw a ray diagram to show how this theory explains reflection.
* '''Question Corner'''

===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.
