When a pencil of ray, diverging from a point, after
reflection and refraction, actually passes through a second
point that second point is called the real image of the
first point.
When a pencil of rays after reflection; and refraction only
appear to pass through a point, the image is said to be virtual.
The difference between the two is that if a image can be
received upon a screen while a virtual image cannot be
received on a screen but can only be seen by the eye.
