## How To Find Curvature Of A Sphere

#### how to determine the radius of curvature for a concave

For example, a round sphere of radius r has Ricci scalar curvature R = 2/r 2 at every point. [With a click of his fingers, a sphere of radius r appears, with a small triangle drawn on it, edges bulging slightly.]

8/03/2011 · Since the normal curvature of the great circle is 1 (because the normal vector to the circle is parallel to the normal of the sphere, and the curvature of the unit circle is 1), the normal curvature of C at p is 1, and the same argument applies to q. So any curve that lies on the unit sphere has constant normal curvature. I think that's right.

Hi again Robert, Suppose that the earth is a sphere of radius 3963 miles. If you are at a point P on the earth's surface and move tangent to the surface a distance of 1 mile then you can form a right angled triangel as in the diagram.

#### 5.4 Curvature Tensors Physics LibreTexts

From this answer, I wish to make it abundantly clear to you that while one sphere can define two mirrors (concave and convex), it takes two spheres to define a lens. In the case of a perfect concave or convex mirror , you can complete the sphere and by the definition of radius of curvature , the radius of the sphere is the same as that of the mirror.

#### Curvature of the Earth Math Central

The sphere has positive curvature, the saddle has negative curvature and the flat plane has zero curvature. A circle drawn on the sphere would have a smaller area than one drawn on the flat plane. While a circle drawn on the saddle would have a greater area than one drawn on …

#### Riemann curvature of a unit sphere Physics Forums

The surplus can, in fact, be used to define a measure for the sphere's curvature (and thus for the difference between its geometry and that of a plane). The elusiveness of curvature But in spite of the differences in geometry, the following still holds: If you look at a tiny region of the sphere's surface, you'll be hard-pressed to find a difference between it and the corresponding region on a
