WebSep 12, 2024 · The radius of curvature is twice the focal length, so \[R=2f=−0.80\,cm \nonumber \] Significance. The focal length is negative, so the focus is virtual, as … 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.
