This is probably painfully simple, and is not a 'brain teaser' as such but this seemed like the most suitable forum. My bro and I were having a discussion tonight and we stumbled across a problem that probably lead to more discussion than it is worth, but since we still can't come up with a proper reasoned answer, I thought I'd post it up here. If you have a video camera, giving a live feed on a T.v say, what would happen (what image would you see) if you pointed the Video Camera at the screen broadcasting the feed. It is positioned so that it is focused only on the screen part of the TV (you cannot see any of the plastic/ etc around the glass screen). Furthermore, the screen is totally clean (no marks of any kind) and also there is no reflection of the camera or anything else on the screen. What do you see? I'd test it out, but don't have a working camera, (although I doubt I could emulate this 'perfect' environment anyway). As I said, it may sound stupid, but there is enough doubts in our minds to put the question to others.
