The correct answer is It is the Centre of a hollow sphere of which the spherical mirror is a part.

Key Points

  • The point in the center of the sphere from which the glass was sliced is known as the center of the curve and is denoted by the letter C in the illustration.
  • This point is equidistant from all points on the reflecting face of the glass.
  • The shaft illustration for the image conformation by a hollow glass when the size of an object and its image are the same is given above.
  • Then, in the illustration, if we put the object in the center of the curve also the image will have the same size as that of the object.

Important Points

  • Mirror Formula:
    • Mirror Formula is given by:-
      \(1/f=1/v+1/u\)1
      ​where,

      f = Focal length of the mirror.

      v = Distance of image from the mirror.

      u = Distance of the object from the mirror.
