1. Concave/Convex Mirror Image Formation Rules Parallel Rays - Light rays parallel to the principal axis are reflected through the focus of the mirror.
2. Focus Rays - Light rays through the focus of the mirror are reflected parallel to the principal axis.
3. Chief Rays Light rays through the center of curvature of the mirror are reflected back along the same path.
