We will be introducing the new Knowledge and Learning Beta website over the coming months. Clips for use in the classroom are now available on your phone, tablet or PC.

Alternatively, you can still browse or search by keyword or clip number on this site.

Key Info
  • Wave refraction
  • Duration: 01:26
  • To produce a laser light show, white light is split into its constituent colours through refraction. A prism is used to slow down different colours of light by different amounts causing them to bend through different angles. The amount of refraction is dependant on the angle the light hits the prism at. Beyond the critical angle, all the light entering the prism is internally reflected. This total internal reflection is the means by which an optical fibre can transmit information from one place to another.
  • Subject:



    Phys: Waves - Sound and Light

  • Keywords: wave, laser, light waves, colour, critical angle, total internal reflection, optical fibres, bitesize telecommunications, physics
Ideas for use in class
  • The clip could link to study of wave refraction. It could contribute to study of fibre optics in both medicine (ie endoscopes) and telecommunications.
Background details
  • Clip language : English
  • Aspect ratio : 16x9
