Measuring the Focal Length of a Convex Lens

Added by Craig Napier on Dec 15, 2008

This activity gives practice measuring the focal length of a set of convex lenses, by placing each lens in front of a distance light source until a clear picture is formed, and measuring the distance from the centre of the lens to the screen.

This item teaches:

  • about the focal length
  • how the focal length is calculated
  • about the focal point of a converging lens
