Question on what a Real and Virtual images are

[pavadrin]

Hi
I was wondering if somebody could kindly tell me what the difference between a real and a virtual image is.
The way I which I know them apart is that in a real image the light rays actually intersect, while a virtual image the light rays diverge , thus never actually intersect. Is this correct?
Thanks

That is correct. A mathematical treatmeant is available here;
