WebbThe focal length of a lens is one way of classifying lenses. The focal length is the distance between the focal point and the lens when viewing a distant object (infinity). The focal length is a constant for the lens. The power of the lens is 1/ f. (1/ f gives the change in wave curvature imprinted on any spherical wave by a lens.) WebbThe following simple formula is established between the distance of the object from the lens ‘p,’ the distance of the image from the lens ‘i’, and the focal length of the lens ‘f.’ 1 o + 1 i = 1 f 1 o + 1 i = 1 f o: Distance from lens to object. It always has positive (+) value. i: Distance from lens to image f: Focal length
