WebAccording to the derivation, the radius of curvature is equal to the toys of focal length in a spherical mirror. Hence we can say that R = 2f. Conclusion The radius of curvature is twice the focal length, or focal length is half of the radius of … WebOct 3, 2024 · The reciprocal of that radius is the curvature. So when walking through a point in the curve where the curvature is $1$, it will feel like a circle of radius $1$, while curvature of $2$ corresponds to a circle with radius $0.5$, and so on. (At least, that is one definition of curvature.)
