The penumbra.
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.
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.
It is called the Umbra, the 'lighter' part of the shadow is the Pen-umbra
No, it's only in shadow when the part we can see is lit.
"Umbra" is Latin for "shadow". "Penumbra" can be translated as "almost shadow".
There are two parts to the Earth's shadow. The dark narrower part is the Umbra (from Latin for shadow). The lighter part is called the Penumbra (from Latin, pane umbra - almost a shadow)
