Focal length of diverging lens
http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/raydiag.html WebRay Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length. The "three principal rays" which are used for visualizing the image location and size are:
