Nature of Light what is colour activity2
Jump to navigation Jump to search
The objective is to understand colours as different wavelengths associated with light.
- Estimated Time - 30 minutes
- Materials/ Resources needed
Computer, projector, power
- Prerequisites/Instructions, if any
- Multimedia resources
- 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)
- How does a wave move? The vocabulary is wave propagation)
- What gets transmitted?
- What can you say about the wave when the frequency is high?
- What can you say about the wave when the wavelength is high?
- 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.
- 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)
- The higher the frequency the higher the energy; this is seen as different colours of the visible spectrum
- Can we break down these seven colours more? (No; demonstrate with a prism; these are pure colours)
- Evaluation (Questions for assessment of the child)
Draw a ray diagram to show how this theory explains reflection.
