Virtual image and Virtual Object

[Omar Nabet]

so virtual image is my image on the mirror? If that was true, then what is a virtual object? (with examples please)

The usual example is, in the vacuum of space particle pairs pop in and out of existence. These are called virtual particles.

That phrase is not appropriate in conventional optics - unless you say that the virtual image from one lens / mirror can be regarded as a virtual object for the next lens / mirror in the chain. But that's only a form of words and doesn't imply that there are really 'virtual objects' anywhere. There's enough to worry about in Science, without exploring all combinations of words that could come to mind. :)
