WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. However, these conventions are arbitrary, and physicists could just as easily have made the signs opposite. WebThe focal length of a mirror is represented as f and is defined as the distance between the focus and the pole of the mirror. The radius of curvature is represented as R and is defined as the radius of the …
