What term is used for the line that passes through the center of curvature of a spherical mirror and the mid-point of the mirror?

optical axis also called: central axis or principal axis

Explanation:

Spherical mirrors can be concave or convex. Every day we find them in our homes: Christmas balls, casseroles, spoons. If you experiment with them you will notice that the image they reflect does not have the same characteristics as in flat mirrors. In reality, these characteristics depend, among other questions, on the type of mirror and the distance at which the object is located.

Main elements of a spherical mirror:

- Radius of curvature: is the radius of the sphere to which it belongs.

- Mirror vertex: it is the cap pole, it is located at the point of contact between the main optical axis and the mirror.

- Main optical axis: is the line determined by the vertex or pole and the center of the curvature.
