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.

What are the turms umbra and penumbra and explain how they relate to eclipses?
You can get three different types of shadows from the moon in total. There is the Umbra (complete shadow where you don't see any of the sun), Penumbra (where the moon covers up one side of the sun - anything from a small 'bite' up to a crescent sun) and then finally there is an Antumbra shadow (where the moon sits completely inside the disc of the sun). During a Total solar eclipse, the observer is in an Umbra shadow, during a partial solar eclipse, the observer is in the penumbra. An annular eclipse is where the observer is in an antumbra shadow and sees the moon completely inside the sun, so the sun appears as a ring.
What are the parts of the eclipse?
And eclipse may be partial or total, or penumbral or umbral. In a total (umbral) eclipse, the umbra of an object's shadow falls upon another object. Umbral solar eclipses are significantly rarer than any other type of eclipse. In a penumbral eclipse, an object's partial shadow, or penumbra, falls upon the other object.

The combined shadows is the "umbra".
