We will see that the curvature of a circle is a constant \(1/r\), where \(r\) is the radius of the circle. The center of the osculating circle will be on the line containing the normal vector to the 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. chiropractic pillows langley
