Fuzzy is an adjective.
The fuzzy edges of shadows are caused by the blocking of light from a light source by an object that is not perfectly opaque. This results in a partial shadow where some light is able to pass around the edges of the object, creating a blurred or fuzzy boundary.
An object's shadow appears fuzzy when illuminated by a large light source because the light rays are not parallel; instead, they spread out over a larger area. This creates a gradient effect at the edges of the shadow, leading to a softer transition between light and dark. The larger the light source, the more pronounced this effect becomes, resulting in a less defined outline around the shadow.
That part of the shadow is called the penumbra.
The largest part of the Moon's shadow is the penumbra.
the darkest part of the moon's shadow is called the umbra
I suppose on some atom models the electron cloud would be called "fuzzy".
The penumbra.
Fuzzy is found in the Moshi Magazine. It is thought that Fuzzy is a Moshi, possibly part of a new set of Moshlings to come out in the future. Fuzzy may not be available or may only be available to those who have a Furi Monster. 001 Fuzzy the Furi [Moshi] Any 3 Hot Silly Peppers
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
There are two parts of a shadow: the UMBRA and the PENUMBRA. UMBRA is the inner darker part of a shadow. PENUBMRA is the outher lighter layer of a shadow. During a solar eclipse, the area on the planet that witnesses a complete total solar eclipse would be under the moon's shadow's UMBRA. The area that views a partial solar eclipse would be under the PENUMBRAL shadow.
It is called the Umbra, the 'lighter' part of the shadow is the Pen-umbra
