Yes, the rays that appear to emanate from a virtual image can be focused on the retina just like those from an illuminated object.
Is it possible to see a virtual image?
Yes, but only indirectly in the sense that if the virtual image is formed on a sheet of photographic film, one could later look at the picture formed.
No, since virtual images do not really exist.
No, since the rays
