The correct answer is real, inverted and enlarged.

Key Points

  •  Magnification of a mirror or a lens is the ratio of the size of the image formed by the mirror or the lens and the size of the object.
  • If the magnification is more than 1, the image is magnified and smaller and if it is less than 1 then it is diminished and enlarged.
  • If the magnification is positive the image formed is erect and virtual and if it is negative the image formed is real and inverted.
  • Here the magnification is -1.38 which is less than 1 so the image is diminished and enlarged , as the value is negative the image formed is real and inverted.
  • So the image formed is real, inverted and enlarged.
