radius of curvature. n. (Mathematics) the absolute value of the reciprocal of the curvature of a curve at a given point; the radius of a circle the curvature of which is equal to that of the given curve at that point. See also centre of curvature.
The curvature of a line or surface is the degree to which it is curved at a particular point. The curvature of the mirror should be gradually reduced towards its edges. A three-dimensional surface which locally resembles that of the surface of a sphere is said to have positive curvature. The curvature of a line or surface is the degree to which it is curved at a particular point.
