Does a person have to be present for an image to exsit? (use operational definition of an image)
for this question I said that, an object need to be present for an image to exsit since an image is the reflection of an object in a mirror or any other shiney surface (its something visual and not physical)
You can generate an image using computer graphics.
Then, if you want, you can reflect that screen image of a mirror.
You said "use operational definition of an image".
Okay, what definition of "image" are you using. Fermat just gave a response that was, I think using a very different definition of "image" than the one you intend. Also, by the way, what is the difference between a "person" and an "object"?
Separate names with a comma.
