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
