Why a ray of light passing through the centre of curvature of a concave mirror,gets reflected along the same path?

Ray optics is a branch of optics that deals with the behavior of light as it travels in a straight line, or ray, through a medium.
In a concave mirror, light reflects off the surface and converges at a focal point. This is due to the curvature of the mirror, which causes the reflected rays to converge towards the center.
A real image is formed when the reflected rays of light actually converge at a single point, whereas a virtual image is formed when the reflected rays appear to be coming from a point behind the mirror. Real images can be projected onto a screen, while virtual images cannot.
The distance between the object and the mirror, also known as the object distance, determines the size and position of the image formed by a concave mirror. As the object distance increases, the image size decreases and the image moves closer to the focal point.
The focal length is the distance from the center of the mirror to the focal point. It is a crucial parameter in ray optics as it determines the size and position of the image formed by a concave mirror. It also plays a role in determining the magnification of the image.
