The region of a shadow that is partially shaded is called the "penumbra." In this area, only a portion of the light source is obscured, resulting in a gradient of light and shadow. The penumbra contrasts with the "umbra," where the light source is completely blocked, creating a darker shadow.

How many types of shadows are there?
In the context of light and shadow, there are three main types of shadows: umbra, penumbra, and antumbra. The umbra is the darkest part of a shadow where all light is blocked, the penumbra is a partially shaded region surrounding the umbra, and the antumbra is the shadow's outermost region where the light source is only partially blocked. These distinctions are important in understanding the behavior of shadows in various lighting conditions.

What is the name of the shadow the moon casts on the earth in its path?
The portion of the shadow the Moon casts on the Earth which is fully shadowed is called the umbra. The portion which is partially shadowed is called the penumbra.
