If several light rays enter a concave parabolic mirror parallel to each other and
to the axis of the mirror, then they'll all converge at the focus of the mirror.
If they enter the mirror from a variety of directions, then there's no telling whether
they might intersect, or where.
A convex mirror bulges out. A concave mirror curves inward.For a convex mirror, light rays are reflected to meet at a point, while, for a concave mirror, light rays seem to be reflected from a point. If the incident rays were paraxial, the reflected rays are reflected to meet at, or appear to be reflected to a point referred to as the focal point of the lens. For a convex mirror, the focal point is real, while, that of a concave lens is virtual.
Parallel rays approaching the mirror are reflected in a converging manner to a focal point.
That passes through the principal focus of the concave mirror

Rays which are parallel to the axis of the concave mirror will converge to the focal point.

It becomes magnified with a concave mirror

A concave mirror will give an elongated appearance. When a mirror curves inward it becomes concave and makes one look elongated and thinner because of the way the light is reflected off the mirror.
it is called concave mirror
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
The incoming light will intersect at a focal point determined by parabolic curve of the mirror.
