  • This type of mirror is known as a concave mirror.
  • A concave mirror has a reflective surface that is curved inward and away from the light source.
  • Concave mirrors reflect light inward to one focal point.
  • Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.
  • Torch lights, automobile headlights are examples of concave mirrors.
  • The mirror used by the dentists to see the teeth of the patients is also a Concave Mirror.
  • Uses of Concave Mirror:

  • The images formed by a spherical mirror can either be real or virtual.
  • Spherical mirrors are of two types:
    • Concave Mirror
