It is called the Umbra, the 'lighter' part of the shadow is the Pen-umbra
"Umbra" means "shadow"; specifically the darkest part of the shadow of a planet or moon during an eclipse.
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.
The dark shadow cast by the Earth on the Moon during a lunar eclipse is called the umbra. This is the central and darkest part of the shadow where the light from the Sun is completely blocked.
No, the umbra is the central, darkest part of a shadow where the light source is completely blocked. In the case of an eclipse, the umbra refers to the region of total darkness where the light source is completely obscured, such as during a total solar eclipse.
The shadow cast by the moon on Earth during a solar eclipse is called the umbra. This is the central, darkest part of the shadow. Surrounding the umbra is a lighter shadow called the penumbra, where only a partial eclipse is visible.
During a total solar eclipse, the umbra or darkest part of the moon's shadow creates darkness on a small section of the Earth's surface. The penumbra is a part of the moons shadow that is more wide spread and not nearly as dark.
I think you are asking what is the lighter part of the Earth's shadow on the Moon that surrounds the darkest part. The penumbra is this lighter part of the shadow. The darkest part is the umbra.
When you are in the moon's shadow during a solar eclipse, it is called the umbra. This is the central, darkest part of the shadow where the sun is completely blocked by the moon. Outside of the umbra is the penumbra, where the sun is only partially blocked, resulting in a partial eclipse.
the darkest part of the moon's shadow is called the umbra
During a total solar eclipse, the shadow is called the umbra. It is the darkest part of the shadow where the moon completely blocks the sun. The umbra creates the area on the Earth where a total eclipse can be seen.
The shadow cast by the moon during a solar eclipse consists of two parts: the inner part, called the umbra, where the sun is completely blocked out, and the outer part, called the penumbra, where the sun is only partially obscured. The umbra creates the darkest part of the eclipse known as totality, while the penumbra creates a partial eclipse effect.
You will see a partial eclipse if you are in the penumbra.
