WebFocal length Focus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of pole and centre of curvature. The distance between the pole and the focus of the mirror is called the focal length of the mirror. Hence, f = 2 R WebNote that the focal length and power of a diverging lens are defined to be negative. For example, if the distance to F F size 12{F} {} in Figure 25.29 is 5.00 cm, then the focal length is f = –5.00 cm f = –5.00 cm and the power of the lens is P = –20 D P = –20 D size 12{P"=-""20"" D"} {}.
