WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. WebThe distance from the center of the lens to the focal point is again called the focal length f f of the lens. Note that the focal length and power of a diverging lens are defined to be …

WebA 39.5-c. A 39.5-cm-focal-length converging lens is 28.0cm behind a diverging lens. Parallel light strikes the diverging lens. After passing through the converging lens, the light is again parallel. What is the focal length of the diverging lens? 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: dvr xfinity
