[edit] Useful Information

  • Light travels in straight lines from a source. Light travels at 300,000 km per second.
  • We see when light from a light source enters our eyes. We would not be able to see if this did not happen.
  • Light can be reflected by shiny surfaces
  • When white light is refracted it can be split into its component colours. These are Red, Orange, Yellow, Green, Blue, Indigo, violet (Richard of York Gave Battle in Vain).
  • Darkness is an absence of light.
  • THE MOON IS NOT A LIGHT SOURCE, IT REFLECTS LIGHT.
  • Objects in front of a light source will create shadows. The closer the object to the light source, the larger the shadow.
