One possibility is that it was put on the paper with lemon juice. You would have to put the paper near a flame (not to the point of igniting it) in order to bring out the image.
Yes. That's a good quick way to determine whether or not a real image exists. You can also use a piece of thin tissue paper, kleenex, or toilet paper, and see the image from the other side. Put a piece of photosensitive material there at the real image, and you get a permanent photo.
you cant
Takes what you see on the screen and puts it on the paper
with your eyes.
If the paper is truly see-through, then it is transparent. If you can see light through it, but not a clear image, then it is translucent.
no you cant see image its appers in waves
If you didn't do anything special to be recognized in the paper, then of course you won't see your face in it. You won't be in it!
because it is folded
Since it does not reflect light. You can only see yourself in a mirror because it reflects light back into your eye, paper does not do this therefore you cant see yourself the reason is that the light rays are reflected in many directions because of the uneven surface.
to identify smaller objects you cant see and to make it into a bigger image
You would certainly be able to see the light from the sun through a telescope, and that's putting it mildly !But it would be foolish and dangerous to do it.Have you ever roasted an ant, or ignited a piece of paper, by focusing a tiny image of the sun with amagnifying glass ? What happened to the ant or the paper is exactly what would happen to the insideof your eye if you focused the image of the sun on it.
A sheet of paper simply isn't shiny or smooth enough. It may seem quite smooth, but actually the particles are quite rougher than the particles of a mirror, for example. Obviously, it isn't a very shiny material.
