Refraction and lenses

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Recall that light can change direction (refract) when it passes across a boundary between transparent media
  • Describe how the angle light passes across a boundary between two transparent media affects how much it is bent (refracted)     
  • Explain why water can appear shallower than it really is      
  • Explain how the shape of a lens enables it to focus light      
  • Explain how light from an object can be focused by a converging lens to form a sharp image

The resources include details of common misconceptions and a summary of the research upon which the resources are based.

Download the zip file for all the questions and activities.
