The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.
For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.
The radius of curvature for a straight line is infinite.

What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
How can find the radius of curvature?
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
Is the focal length equal to the radius of curvature of the mirror?
yes
How do you calculate the radius of curvature for the curve?
See the following link.
What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
How do you find radius of curvature if focal length is given?
radius of curvature = 2Focal length
What is radius of curvature?
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
What is the difference between Radius of curvature and centre of curvature?
The radius of curvature is the distance from the center of a curved surface or lens to a point on the surface, while the center of curvature is the point at the center of the sphere of which the curved surface is a part. In other words, the radius of curvature is the length of the line segment from the center to the surface, while the center of curvature is the actual point.
How can find the radius of curvature?
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
What is Radius of curvature of a lens?
The radius of curvature of a lens is the distance between the center of the lens and its focal point. It is a measure of the curvature of the lens surface. A smaller radius of curvature indicates a more curved lens, while a larger radius indicates a flatter lens.
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
Give The formula for radius of curvature in polar form?
The radius of curvature is given by(1)where is the curvature. At a given point on a curve, is the radius of the osculating circle. The symbol is sometimes used instead of to denote the radius of curvature (e.g., Lawrence 1972, p. 4).Let and be given parametrically by(2) (3)then(4)where and . Similarly, if the curve is written in the form , then the radius of curvature is given by
What does curvature of radius of a lens effect?
The curvature of the radius of a lens affects its focal length and optical power. A lens with a shorter radius of curvature will have a shorter focal length and higher optical power, while a lens with a larger radius of curvature will have a longer focal length and lower optical power.
When curvature radius is larger what happens to the focal point?
When the curvature radius is larger, the focal point moves closer to the lens or mirror. This is because the curvature radius affects the focal length – a larger radius results in a shorter focal length and thus a closer focal point.
What is the curvature of circle having radius a?
1/aAccording to Wikipedia,"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
