REAL IMAGE ; THE REAL IMAGE IS THAT IMAGE WHICH IS FORMED WHEN THE LIGHT RAYS COMING FROM AND OBJECT ACTUALLY MEET EACH OTHER AFTER REFLATION OR REFRACTION. VIRTUAL IMAGE; THE VIRTUAL IMAGE IS THE IMAGE WHICH IS FORMED WHEN THE LIGHT RAYS COMING FROM AND OBJECT DO NOT ACTUALLY MEET BUT APPEAR TO MEET WHEN PRODUCED BACKWARD.

real and virtual image '' plane mirror a virtual image is produced when rays of light reach our eyes that appear to come from a real object , but there is in fact no object at the apparent source of the light . the most common example is when light from an object strikes in simple plane mirror .

a virtual image is an image formed when the outgoing rays from a point on an object always diverges the image appears to be located at the point of apparent divergence 
a real image one that is formed when the when the outgoing rays form a point converge at a real location real image can be seen on a reflecting screen but a screen is not necessary for the image to form

in optics, a  virtual image is an image formed when the outgoing rays from a point on an object always diverge.the image  appears to be located at the point of apparent divergence.because the rays never really converge, a  virtual image cannot be projected onto a screen. In diagrams of optical systems, virtual rays are conventionally represented by dotted lines

*it can be seen that the light rays appear to emanate from the virtual image but do not actually exist at the position of the virtual image.
*the image virtual image.
