the imaginary line passing through the the center of curvature and pole is called the principal axis.
That passes through the principal focus of the concave mirror
It is reflected back parallel to the principal axis. (apex)
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected through the focal point of the mirror after reflection.
It reflects out through the focus.
When light hits a concave mirror parallel to the principal axis, the reflected light rays converge at the focal point of the mirror.
To draw the principal axis for a concave mirror, start by sketching a horizontal line that represents the principal axis. Then, draw the concave mirror as a curved line facing the incoming light, with the reflective surface on the inside of the curve. Mark the focal point (F) on the principal axis at a distance equal to the focal length from the mirror's surface, and indicate the center of curvature (C) at twice that distance (2F) from the mirror. This principal axis is essential for understanding how light rays reflect off the mirror.

When a small object is placed on the principal axis of a concave mirror between the focus and the mirror, a virtual and upright image is formed behind the mirror. The image is magnified and located further away from the mirror than the object.
The line joining the pole and the centre of curvature of a mirror is called the principal axis. This line is a key reference point for determining the focal length and characteristics of the mirror.

The center of a spherical mirror is called the vertex. This is the point where the principal axis intersects the mirror's surface.
Any ray that travels parallel to the principal axis of a concave mirror will reflect through the mirror's focus after reflection. This is known as the "law of reflection" for concave mirrors.
