Hii friends
Where there is no light there is darkness, we call this a shadow. In fact at night we are in the shadow of the Earth.You can see from the two diagrams that there are two types of shadow; a crisp edged one formed by a point source of light and a rather more fuzzy one that is formed by a larger source.

The region of deep, total shadow is called the umbra and the region of partial shadow is called the Penumbra. The umbra is a region where no light can get to while the penumbra is a region where some light can reach.
