An umbra is formed when an object blocks all of the light from a light source. A penumbra is formed when light from one source is blocked with light from another source filling in some of the shadow, OR when a large light source is only partially blocked.

The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
During the eclipse, the penumbra is the outer part of the shadow where only partial sunlight is blocked.
Shadows have two parts, the umbra and the penumbra. The umbra is the darker part of the shadow, in which all of the light from the source is blocked by the object casting the shadow. The penumbra, also known as the half-shadow, is the grayish part along the edge of a shadow in which only some of the light from the source is blocked.During a solar eclipse, if you are within the umbra of the moon's shadow, you are witnessing a total eclipse, and if you are within the penumbra of the moon's shadow, you are witnessing a partial eclipse.
In a solar eclipse, no sunlight penetrates the umbra. This is because the umbra is basically the shadow of the Earth, so in this case, the Earth is receiving the sunlight from the Sun, while both the umbra and moon are in the dark.
You are in the umbra, the darkest part of the moon's shadow, if you see a total solar eclipse. This is where the sun is completely blocked out, creating a moment of totality.
The umbra is associated with a total eclipse, penumbra with partial.
an umbra is the center of the solar eclipse which is the darker part and the penumbra is farther away from the center of the eclipse and is brighter than the umbra
The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
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.
During the eclipse, the penumbra is the outer part of the shadow where only partial sunlight is blocked.
Umbra and penumbra when referred to the moon describes the shadow which is formed when light is blocked from the sun, by the moon. This shadow which falls on the Earth and has two distinct regions; a partially shadowed area which is the penumbra and the centre point a totally dark umbra. We on Earth looking skyward and watching the shadow pass as the Earth revolves would describe the penumbra as a partial eclipse and the umbra as a total eclipse.

penumbra or umbra.
one is behind the other or caused by the other
You are in the umbra, the darkest part of the moon's shadow, if you see a total solar eclipse. This is where the sun is completely blocked out, creating a moment of totality.
