We can't see our picture because the surface of the cardboard is rough, and the reflection that occurs on an uneven surface is an irregular reflection. As a result, the rays go in different directions following reflection. Images do not develop as a result of uneven reflections. The image on the table is also called a ghost image because it looks like a picture of someone or something else. Ghost images are often seen in optical instruments such as telescopes where there are mirrors or lenses that reflect or refract light from objects far away. These devices use complex mathematics to calculate the position of objects which cannot be seen directly due to their distance from us. For example, when viewing stars with the naked eye, only the brightest ones can be seen. Using a telescope with a lens, one can see objects that would otherwise be invisible. Telescopes work by using glass lenses or mirrors to bend light toward the viewer. When light is reflected off of an object, the resulting image is called a ghost image because it appears as if something else is being viewed. Ghost images can also be seen by looking into clear water such as lakes or ponds. This is because every object that lies beneath the surface creates its own ghost image. So if there is no visible object under the surface, then there should be nothing there to reflect back up towards the viewer. It is important to understand that ghosts images are simply reflections of objects distant from each other.
