What properties of light define it as a wave?
An experiment was conducted in relation to this theory. A extremely small object (dot0 was placed in the path of light. If light is considered to be traveling in straight lines, then a small shadow should have been formed. However, in this case no shadow is formed. Meaning that light has bypassed the object... Such bypass is only possible when light is wavy in nature... How light is both wavy and particle in nature.
What is a example solid object with no shadow?
Trick question or a question asked by someone who doesn't truly understand the issue. One can say that colorless polished glass or clear plastic has no shadow. Probably the answer your teacher is seeking. But this is not true. Even glass is not perfectly transparent and casts a small shadow. Perhaps a shadow barely perceptible to the human eye, but it is there. It is possible to have a luminous solid object emit the exact amount of light to cancel its shadow, but this isn't really having no shadow, is it? Your teacher will not like this answer. If we REALLY want to confuse them, we can speak of metamaterials.
Describe the attitude and approximate size of the image when an object is very close to and far from a convex lens?
When the object is close it is big and upright when far away it is small and upright also
What type of shadow is produced by a small lamp?
a small shadow
Which would take less force to move a heavy object or a light weight object?
When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
When you place something close to a light source will it make a big shadow or a small shadow?
The closer an object is to a source of light the larger the shadow it will cast.
What creates a shadow?
The word shadow has many meanings in English. Most of these refer to the shielded area behind an object which relates to its original Old English meaning of "shield" or "block"/ Thus a shadow is created when an object blocks light, wind , rain or other force to produce a dark, calm or dry area.A shadow, meaning an entity or thing that closely follows another, such as a shadow government a shadow in police work relates to the fact that a "shadow" is close to the object creating the shadow and mimics the objects size and movement. Other concepts for shadow include "darkness". A room with small windows is said to be "in shadow" This type of shadow is created in an interior which is protected from the light.
What is the difference between a shadow of an object created by a small light source and the sun?
Shadow from light source always bigger than object but shadow from the sun is the same size as object. Great different is due to the distance of light source. Size of shadow is double at distance x 2 source to object. Shadow is always bigger than object. You will notice your shadow is bigger in light bulb or stadium spot light but the shadow from sun is the same size as object. This is due to great distance from sun to us (150 million km approximately) the double distance to see our shadow to be double is at 300 million km from the Sun. at merely 10 m or 100 km is almost no distinguishable different in shadow size to the object. We then presume shadow cause from sunlight is equal to the size of the object.
Is a shadow translucent?
The shadow is not a solid 'black' colour. It can be the same colour as the object and the shadow allows you to see through it more than an opaque objects shadow. An opaque object would block the light but a translucent object would give a shadow that you could quite easily see through

How would a shadow change as an object moves toward the light source?
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

What does ghost shadows mean when there small?
Ghost shadows refer to faint, shadowy outlines or images of an object that linger momentarily after the object has moved. When they are small, they may be caused by dim lighting conditions or the object being close to the surface the shadow falls upon.
What is the small light of the moon called?
if you mean the small shadow, its the penumbra
How big can shadows be?
Size of shadow depends on its distance frm source of light.when object is vry clos 2 src of ligt the shadow formed is very big but when object is far , the shadow is small.
What makes a big shadow so blurry?
I've had to make some assumptions about what you're really asking here; if I'm wrong, please clarify your question and ask again. A "big" shadow usually happens when the object casting the shadow is a long way from the surface it's casting the shadow on. Light refracts and spreads, and the more distance it has to do this in, the more it refracts and spreads. The combination of the two factors means that a "big" shadow, where the surface is a long distance from the object casting the shadow, is likely to be more blurry than a "small" shadow where the object is near the surface.
How does the size of the source affect the shadow of the object?
A bigger source will cast a fuzzier, less distinct shadow. A single point source, infinitely small, will on the other hand cast a perfectly defined shadow with an abrupt edge. The shadow is likely to be a good image of the object that casts it. But imagine standing in the shadow of an object shading you from a larger light source, like the moon. As you move your head, sometimes the moon's disc will only partially be obscured, and sometimes completely. The area of the shadow where the light is only partly blocked is the penumbra. A limited region of the shadow is shaded entirely from the light source: this is the umbra. The specific effect of enlarging a light source is to make the penumbra bigger and the umbra smaller. More areas will receive less than 100% of the light, but a smaller area will be 100% shadow - hence the blurring effect. Light and shadow are more evenly distributed. Overall, the area in some degree of shadow will increase. Try observing the shadow of your finger under artificial lighting at home: the dark umbra should be visible, and the grey penumbra where the shadow fades continously away to nothing. The blurring will also be exacerbated by moving your finger away from the surface onto which its shadow falls. Note that it is the angular size of the source that really matters. The sun is huge, but since it is so distant its angular diameter is only half a degree, so it casts fairly sharp shadows.
