Light from a source forms shadows and can be absorbed, reflected and refracted (ACSSU080)

Elaborations
  • drawing simple labelled ray diagrams to show the paths of light from a source to our eyes
  • comparing shadows from point and extended light sources such as torches and fluorescent tubes
  • classifying materials as transparent, opaque or translucent based on whether light passes through them or is absorbed
  • recognising that the colour of an object depends on the properties of the object and the colour of the light source
  • exploring the use of mirrors to demonstrate the reflection of light
  • recognising the refraction of light at the surfaces of different transparent materials, such as when light travels from air to water or air to glass

Light and reflection: using mirrors

Change the direction of a light beam using a mirror. Light the way for a scribe to see inside a pyramid. Position mirrors to direct a beam of sunlight. Choose mirrors that will reflect light at a suitable angle. Find animals on a dark night. Choose a mirror that will reflect light at a suitable angle. Notice that the light ...

Light and reflection: light rays

Investigate whether light rays always travel in straight lines. Rotate circular walls, each of which has a single opening. Position the walls so that light from a central bulb can be seen by a person outside the walls. Make shadows by placing a range of objects between a light source and a screen. Position shapes to make ...

The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?
