Detailed explanation-1: -A ray of light passing through the focus of a concave mirror will be reflected parallel to the principal axis of the mirror.
Detailed explanation-2: -Answer: A ray of light parallel to the optic axis of a concave mirror is reflected back through the focal point.
Detailed explanation-3: -Refraction Rules for a Converging Lens Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.
Detailed explanation-4: -An incident ray traveling through the focal point will reflect and travel parallel to the principal axis. An incident ray traveling through the center of curvature will reflect and travel back along the same path from which it came.
Detailed explanation-5: -A ray passing through focus of concave mirror will be reflected parallel to the principal axis.
