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: WebThe direction of light rays travelling through the centre of converging or diverging lenses does not change. Light rays that enter a converging lens through its focal point always exit parallel to the lens's axis. On the other side of a diverging lens, a light ray going towards the focal point will also emerge out parallel to its axis.
