 The Question

Any ray of incident light that passes through the focal point and strikes a concave mirror will reflect and _____.

 Physics Rules

Concave Mirrors - Rules of Reflection
Light reflects off any surface - plane mirror, curved mirror, or non-mirror - according to the law of reflection. For concave mirrors, some generalizations can be made to simplify ray construction. They are:
  • An incident ray traveling parallel to the principal axis will reflect and pass through the focal point.
  • 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.
