Nature of Light what is colour activity2

The objective is to understand colours as different wavelengths associated with light. Computer, projector, power
 * Estimated Time - 30 minutes
 * Materials/ Resources needed
 * Prerequisites/Instructions, if any
 * Multimedia resources

Watch the video and discuss with the student their understanding. Draw a ray diagram to show how this theory explains reflection.
 * Website interactives/ links/ simulations
 * Process (How to do the activity)
 * Developmental Questions (What discussion questions)
 * 1) How does a wave move? The vocabulary is wave propagation)
 * 2) What gets transmitted?
 * 3) What can you say about the wave when the frequency is high?
 * 4) What can you say about the wave when the wavelength is high?
 * 5) It is possible to look at light as a wave; the waves are not of material objects but travelling waves changing electric and magnetic fields.
 * 6) Different wavelengths are associated with different energy levels and different kind of radiation(light is a form of electromagnetic radiation; there are other electromagnetic radiations)
 * 7) The higher the frequency the higher the energy; this is seen as different colours of the visible spectrum
 * 8) Can we break down these seven colours more? (No; demonstrate with a prism; these are pure colours)
 * Evaluation (Questions for assessment of the child)
