Derivation of radius of curvature

WebSep 7, 2024 · The curvature of the graph at that point is then defined to be the same as the curvature of the inscribed circle. Figure \(\PageIndex{1}\): The graph represents the curvature of a function \(y=f(x).\) The sharper the turn in the graph, the greater the curvature, and the smaller the radius of the inscribed circle. 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 expected for a concave mirror and a real object. The radius of curvature found here is reasonable for a cornea. The distance from cornea to retina in an adult eye is about 2.0 cm.
