LIGHT

  • There has to be energy to make a change and a movement.
  • White light can be decomposed into different colours. (rainbow)
  • The colours of the rainbow are red, orange, yellow, green, blue, violet and indigo.
  • Light travels in a straight line.
  • When a ray of light hits a prisme it makes a rainbow.
  • Transparent is when you can see light totally through an object. (ex: window)
  • Translucide is when you can see a bit of light through an object. (ex: kleenex)
  • Opaque is when you can't see any light through an object. (ex: walls)
  • A shadow is an abscence of light.
