Virtual image

A virtual image of a light reflective or luminous object is in optics, an optical image that unlike a real image can not be displayed on a screen. In converging lenses it is formed when the object is between the focal point and the lens.

From the location of the virtual image go no light rays from (hence the term "virtual" ), but the rays appear to come from the image here, because our perception subordinated light rays as straight and the eye- striking beam, if necessary, produced backwards.

Important examples are:

  • The mirror image in a plane mirror. It is located behind the mirror ( even if there is a wall ) at the same distance as the object and has the same size as that (even if the mirror is much less ).
  • The motion image, generates a focusing lens of an object located within the focal length.
  • The image that we perceive of an object when viewed through a diverging lens.
