If the light source is fairly large, it will create a total shadow, when the entire light source is blocked, and partial shadow where only part of the light source is blocked. The "umbra" is the area of total shadow, while the "penumbra" is the area of partial shadow.
The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
