The umbra in a shadow is the portion where light from a source is completely blocked. This is in the middle of the shadow.
The area around this, where light from part, but not all of the source shines is called the penumbra.
In the shadow cast by the moon in an eclipse, the penumbra is the partial shadow that occurs before the total eclipse, and the umbra is the 'total eclipse' portion

You can see this at home. Place two lamps close to each other. Hold up a plate. Notice that the plate throws a shadow from each lamp. The darker shadows, where the plate blocks both lamps, is the "umbra". The part of the shadow from one lamp is the "penumbra".

∙ 13y agoYes, the penumbra is the outer part of a sunspot. The umbra is the center.
Wiki User
∙ 14y agoYes it is because the umbra is in the shadow so it is in the inner part of the shadow
Wiki User
∙ 13y agothe umbra is the dark part of the shadow
the penumbra is transition between the lit region and the totally dark umbra. in the penumbra the light source is not completely covered.

Standing in the penumbra, part of the sun is blocked from your view, but part of it is still visible.

Is this true or false total solar eclipse can be seen only by people in the area of Earth within the Moons umbra?
True. The umbra is the central darker total shadow of the Moon. Outside of this area, called the penumbra, is the lighter partial shadow. In this area, you would see a partial or annular eclipse. The umbra and penumbra are cone-shaped areas of full and partial shadow. The solar eclipse of January 14, 2010 (last week, as I write this) the Moon was so far away from the Earth that the umbra didn't reach all the way to the Earth. So the Sun was visible all the way around the Sun; and "annular", or ring-shaped eclipse.

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.
