Question

With the help of a suitable diagram, explain the meaning of terms radius of curvature ​

Answer 1

Answer:

In differential geometry, the radius of curvature, R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof.

Answer 2

Answer:

Answer: The diagram shows a convex lens. ( a ) Centre of curvature - center of curvature of a curve is found at a point that is at a distance from the curve equal to the radius of curvature lying on the normal vector. It is the point at infinity if the curvature is zero.
