A glass object would give the darkest shadow because it is a transparent material that allows very little light to pass through it, resulting in a more defined and darker shadow compared to the other options provided.
The darkest part of a shadows is called the "umbra", which is actually Latin for "shadow". This is where the light source is completely blocked by the occluding body. The person viewing the umbra experiences a total eclipse.
A complete area of shadow is called an umbra. It is the darkest part of a shadow where no light reaches.
The object's shadow appears larger than the object because the sun's rays hit the object at an angle, causing the shadow to stretch away from the light source. This creates the illusion of the shadow being larger than the object itself.
The penumbra.
Yes, a shadow can be smaller than the object casting it. This can happen when the light source is very close to the object or when the object is very close to the surface on which the shadow is cast. The size of the shadow is determined by the angle of the light rays hitting the object and the distance between the object and the surface.
the darkest part of the moon's shadow is called the umbra
The darkest part of a shadow is called the "umbra" The lighter part of a shadow is called the "penumbra" An "antumbra" is the area of light which surrounds the object creating a shadow, as in a "ring of fire" eclipse (like the recent one in May, 2012). It can best be seen when the viewer is beyond the focal point of the umbra, but in line with it.
The darkest part of the moon is called the Umbra. That is the darkest not the largest.
The darkest part of a shadows is called the "umbra", which is actually Latin for "shadow". This is where the light source is completely blocked by the occluding body. The person viewing the umbra experiences a total eclipse.
The darkest, "total" shadow is called the "umbra", while the partial shadow is called the "penumbra", from the latin prefix "pen" meaning "almost".
No, a shadow cannot have only an umbra. A shadow is formed by a combination of different parts, including the umbra (the darkest part), penumbra (a lighter surrounding area), and antumbra (a region beyond the umbra where the light source is partially blocked by the object casting the shadow).

The penumbra
The darkest portion of the Moon's shadow during a total solar eclipse is called the umbra. It is the region where the Sun is completely blocked and only the Moon's shadow falls on Earth, creating the darkest point of the eclipse.
Sunspot
A complete area of shadow is called an umbra. It is the darkest part of a shadow where no light reaches.
It is called the Umbra, the 'lighter' part of the shadow is the Pen-umbra
