What is penetration of light into a region of geometrical shadow called?
The penetration of light into a region of geometrical shadow is called "penumbra." This occurs when only partial obstruction of light causes a partial shadow to be cast.
What are the names of the two parts of the moon's shadow?
The two parts of the moon's shadow are the umbra, which is the dark central region where light is completely blocked, and the penumbra, which is the lighter outer region where only partial light is blocked.
What are the outer blurred edges of a shadow called?
The outer blurred edges of a shadow are called the penumbra. This region is where the shadow transitions from complete darkness to partial darkness, resulting in a softer edge.
What is called when only a region around the edge of the moon is lit up by the sun?
A partial lunar eclipse occurs when only a portion of the moon enters Earth's shadow, creating a distinctive crescent shape as only a region around the edge of the moon is lit up by the sun.
What is the outer portion of the shadow cast on Earth by the Moon called?
The outer portion of the shadow is called the "penumbra".

What is a Partial shadow?
a partial shadow is a penumbra
What is penumbra?
Penumbra is a partial outer shadow that is lighter than the darker inner shadow umbra (e.g. the area between complete darkness and complete light in an eclipse). It is a fringe section of half shadow resulting from the partial obstruction of light by an opaque object.

The outer portion of the shadow is called the "penumbra".
What is partial shadow?
penumbra The Latin word "umbra" means "shadow". The prefix "pen-" means "almost" or "partly", so "penumbra" means a partial shadow.
What is the name of the partial area of a shadow?
Penumbra
What does the Moon enter when a partial lunar eclipse begins?
It first enters the penumbral shadow, or outer shadow caused by the Sun shining "around" the Earth. For a "partial" lunar eclipse, the Moon eventually but only partly enters the dark red "umbral shadow." If it doesn't, the eclipse is called a penumbral eclipse.
Is it true that the umbra is the inner part of the 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.
What are unmbra and prenumbra?
Umbra refers to the darkest part of a shadow where light is completely blocked by an object. Penumbra is the partial shadow region surrounding the umbra where some light is still able to reach. These terms are commonly used in astronomy and for understanding eclipses.
