    Relates object distance, image distance, and focal length for mirrors.
  • Spherical Mirror
    A mirror shaped as if it were part of a sphere.
  • Radius of Curvature
    The radius of the sphere from which a spherical mirror is shaped.
  • Focal Length
    Half the radius of curvature for a spherical mirror.
  • Concave Mirror
    A converging mirror with a positive focal length.
  • Convex Mirror
    A diverging mirror with a negative focal length.
  • Real Image
    An inverted image formed by converging light.
  • Virtual Image
    An upright image formed by diverging light.
  • Magnification
    The ratio of image height to object height.
  • Sign Convention
    Rules determining the signs of distances and focal lengths in mirror equations.
  • Plane Mirror
    A mirror with an infinite focal length, producing virtual images.
  • Image Distance
    The distance from the mirror to the image.
  • Object Distance
