Product Description

Video and lesson investigations on the topic of refraction. Key concepts include:

  • Water changes what we see (it bends the light).
  • The light coming from an object underwater is bent (refracted) at the water’s surface.
  • Objects in water appear to be in a different place from where they really are.
  • The apparent shift in position depends on both how far the object is below the surface of the water and the position from which it is viewed.
  • Light travels more slowly through water or glass than it does through air because water and glass are more dense than air.
  • As light slows down, it also changes direction slightly.
  • This difference in the speed of light makes objects that are half in the water and half in the air look ‘bent’.
  • This phenomenon is called ‘refraction’.
