Reflection, Refraction and Absorption of Light (AC9S5U03)

identify sources of light, recognise that light travels in a straight path and describe how shadows are formed and light can be reflected and refracted

Choose a learning activity. Practice and Test use short shuffled attempts. Repeat quiz practice to access more of the full question bank.

Unit focus

  • Students trace rays from a source, explain reflection from surfaces, refraction when light changes medium, absorption by materials and shadow formation when opaque objects block light.
  • Use evidence to trace a ray to the eye.
  • Watch for eyes send out light to see: Light from a source reaches objects and then the eye.
