It's an Optical Axis.
The main parts of a concave mirror are the pole (center point), principal axis (imaginary line passing through the pole and center of curvature), focal point (half the distance between the pole and center of curvature), and the center of curvature (center of the sphere from which the mirror is a section).
along its axis in the center
The line passing through the center of the lens perpendicular to its curved surfaces is called the principal axis. This axis is used as a reference point for measuring distances and angles in optics. It helps determine the focal point and focal length of the lens.
No, the center of a concave lens is thinner than its edges. Concave lenses are thinner in the middle and thicker towards the edges, causing light rays passing through them to diverge.
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.

The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
The term that indicates an imaginary line extending straight out from the center of a reflective surface is called the "normal line." This line is perpendicular to the surface at the point of incidence where light strikes the reflective surface. It is essential in understanding the angles of incidence and reflection in optics.

The term that indicates the imaginary line extending straight out from the center of a reflective surface is called the "normal line." This line is perpendicular to the surface at the point of incidence, where a light ray strikes the surface. It is used in optics to analyze the behavior of light as it reflects off surfaces.

along its axis in the center
-- Draw any two random chords of the circle. -- Construct the perpendicular bisector of each chord. -- The perpendicular bisectors intersect at the center of the circle. All of this can be done with a compass, an unmarked straight-edge, and a pencil.
The Prime Meridian does not divide the Earth, it is an imaginary line going straight through the center.
