No, a shadow is a concept, like cold, which is the absence of another thing (light for a 'normal' shadows or energy for shadows in general, heat for cold). As such, shadows are not made, but exist in areas absent of energy.
yes because if you put an opaque object in the sun it makes a shadow because it is not transparent
A shadow is formed when an opaque object blocks the travel of light on a second object. Light travels in straight lines and any barrier along its path averts the rays striking the barrier.This forms a region of darkness, shaped like the surface of the object obstructing the light. A shadow takes up all the space behind the object with light before it. Its cross-section is a two-dimensional outline of the obstructing object. The shadow is smaller if the angle between an object and the path of light is nearer to 90°. It is longer if the angle between the surface and the path of light is smaller. If the obstructing object is closer to the starting point of light, the shadow is larger.
An object (Materials) that does not allows anylight to pass through will form a shaddow:Eg.- Opaque ( Can't let any light to pass through)- Translucent (Allows a little bit of light to pass through)If you want to make sure Im correct do this experiment:Instruments:- A Cloth ( Opaque)- A torch- A Tracing paper ( Translucent)- A screenPlaces to do:- A dark roomHow to do? :- Use your torch and shone on the cloth facing on the screen, what will you see?- Use your torch and shone on the tracing paper on the screen, what will you see?You will see an unclear shadow and a clear shdow on the screen! You may also add one more item a Transparent object! You will see I'm quite correct...Shadows are formed by light, because if light shines onto an object, and the object blocks the light, the light will go sideways of the object, and therefore, a shadow is formed.Light can only travel in straight lines. If light is coming from one main source, then an object that does not allow light to pass through it, will have an absence of light behind it, i.e.a shadow.
because the light bulb made the gray halo have a shadow
The size of shadow an object casts, is directly related to the position of a light source. the higher up a light source is in relation to the object, the shorter the shadow will be. Shadows cast by objects lit by the sun in the morning or evening are long, because the sun is low in the sky. At mid-day, the shadow is shorter because the sun is higher. Try it yourself with a torch - and see !
when you heat an object up what happene to the atomsmolecules that it is made of?
I don't know if I have misunderstood this question, but dark is the absence of light. The only darkness that I can think of which is made by light are shadows, when light rays are blocked by an opaque object.
it is from the sun which gives light. when an object is in front it blocks the light and becomes a shadow.
It occupies all of the space behind an opaque object with light in front of it.
i think it is about the object that makes the shadow
shadows are made of a dark matter called eucloid which emerges out of the object only in darkness
A silhouette is named after Etienne de Silhouette who loved hand-cut silhouettes for their frugal quality. A good silhouette is not made from a shadow, it is hand-cut by a real artist. Shadows come from blocked light reflectd off an object. In Jung, the shadow is the dark side of a person.

Shadow
A shadow is formed by an object blocking direct light, this causes the light to travel around the object, forming a shadow. The best way to test this is by standing in direct light from a street lamp.The closer you move towards the direct light, the fuzzier the shadow will be, however the more far away from the direct light, the shadow will become crisp and more detailed. ^----^ [ O.0] / )
In this Thread, we will become familiar with the orientation of shadows, their size in relation to the object casting them, and how the alignment of the Sun, the object, and the shadow tells us much about how shadows work. The National Science Education Standards stress that geometry and light should be integrated into curricula as tools for learning about three dimensional objects. Vocabulary words which can be used to help talk about our experiences are alignment, casting, angle, and light source. The height of a tilted light source (in other words, the angle between the light source and the ground) and the size of the object it is illuminating determine the length of the shadow that the object casts. The object blocks the light coming from the source so that nothing behind the object gets any direct light. The length of the shadow is a result of how high above or below the top of the object the light source is. Imagine if the light source were directly above the top of the object. Would there be a shadow? No, not one that would be visible around the object. Twist the light source a little down from the top, and a shadow appears behind the object, but is very short. This is because as the light source moves down, the shadow is being created by the small area of the object blocking the light. Imagine straight lines coming down from the light and hitting the object. The higher the light, the less light lines get blocked by the object and hence the less shadow. Thus, the lower the light source is aimed at the object, the more the object blocks the lines, or rays, of light. The key to understanding shadows is to realize that the light source and object must be lined up in order to make a shadow appear. In fact, if the object is placed anywhere along that line, it will produce a shadow of the same length behind the object. It is only when you change the orientation of the light source that the shadow changes. That makes sense in one order: light hits an object and casts a shadow. But experiencing the connection of these fundamentals in a different arrangement is good for rooting our experiences more firmly. In other words, trying to predict where to place an object to cast a shadow at a specific location: essentially trying to locate the path of the light. We've made a brief page about solar eclipses. Solar eclipses are excellent examples of light and shadow. By JASON
