A ray parallel to the principal axis strikes a concave mirror. After reflection, it passes through which point?
The focus of the mirror
It is a standard rule of reflection for a concave mirror that any ray travelling parallel to the principal axis converges through the principal focus after reflection.
Hence, the reflected ray passes through the focus of the mirror.
