What is the outline or form of an object called?
The outline or form of an object is called its silhouette. It is the shape or contour of the object when viewed from a distance or against a light source.
How do diffraction spikes in vision affect the perception of light sources?
Diffraction spikes in vision can cause light sources to appear as if they have spikes or rays extending from them. This can distort the perception of the light source's shape and intensity, making it appear different from its actual form.
How is a shadow created and what factors influence its formation?
A shadow is created when an object blocks light, causing a dark area to form behind it. The size and shape of the shadow depend on the angle of the light source, the distance between the object and the surface where the shadow falls, and the properties of the object itself. Other factors that influence shadow formation include the intensity and direction of the light, as well as the presence of other objects that may also block or reflect light.
How can we form a rectangular shadow by a circular bottle cap?
You can place the circular bottle cap on a flat light source such as a table, paper, or wall and shine a light directly on it from above. The shadow cast by the circular bottle cap will appear as a rectangular shape due to the angle and distance of the light source. By positioning the circular object and light source correctly, you can create the illusion of a rectangular shadow.
Why do opaque objects form shadow?
Opaque objects block light, so when light hits them, they cast a shadow on the surface behind them. This occurs because light cannot pass through the opaque object, creating a region of darkness where light is prevented from reaching. The size and darkness of the shadow depend on the intensity and angle of the light source.
As photons travel further form the source of light theintensity of the light?
decreases in proportion to distance from the object squared. A good example in the link below.

What is the HID Flashlight?
HID means High Intensity Discharge and is a modern form of lighting in which a compact arc is used as the source of light. They are more efficient that halide lamps.

What is source light?
A light source is a form of energy produced by heat.
How is faint shadow form?
A faint shadow is formed when an object partially blocks light from a light source, creating a less defined silhouette compared to a sharp shadow. The intensity of the shadow depends on the distance between the object and the surface where the shadow falls, as well as the strength and angle of the light source. Diffused light, such as that from cloudy skies or indirect sources, contributes to the creation of faint shadows by softening the edges. Additionally, the color and texture of the surface receiving the shadow can affect its visibility and clarity.
Why does a shadow form beside the cup and saucer?
A shadow forms beside the cup and saucer because they obstruct the path of light from a source, such as the sun or a lamp. When light hits the objects, it creates an area of darkness on the surface next to them where the light cannot reach. The size and shape of the shadow depend on the angle and intensity of the light source, as well as the position and dimensions of the cup and saucer.

Is white paper a form of a light source?
No
Why does a shadow form behind the tree?
A shadow forms behind a tree when an object, like the tree, blocks the path of light from a source, such as the sun. The light cannot pass through the solid object, and as a result, an area of darkness— the shadow— is created on the ground or surface behind the tree. The position and length of the shadow change depending on the angle and intensity of the light source.
