Answer:
The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. Assuming no diffraction, for a collimated beam (such as a point source) of light, only the umbra is cast.

Answer:
Explanation:
The temporary art - such as public art that is exhibited only for a short amount of time or visual performances - can't be experienced by everyone and in a longer period. Therefore, the only way to preserve this art is to document it via text, video or a photograph.
<u>We must expect that the art won't stay the same and provoke the same feelings as the original, temporary art. </u><u>Seeing something in real-time and in real life, experiencing the movements, the size of it, the three-dimensionality, is something that is different from anything else. That is why the art is exhibited or performed in the first place, even if for a temporary time.</u>
What we can expect is to change the focus of art.
This does mean the art will become more two dimensional. However, we can provide that documenting it becomes another, a special form of art that will save the part of original quality, but that will absorb qualities of another form of art.
<u>If we photograph the temporary sculpture in the public space, we can provide that the way we photograph it (aerial photography, with many spectators, isolated, in a different light) expands some of its qualities. If we make the video of the performance, we can use special techniques that are used in filming to accent certain aspects of the performance.</u>
<u>Therefore, while the art will lose some of its three-dimensionality it will gain different qualities and will transform itself into a completely different medium of the art piece.</u>
