Formation of Shadows ( Umbra Prenumbra Antumbra )

When the earth or moon fall between the sun and one another shadows are created. In this video, I demonstrate what an umbra, penumbra and an umbra look like.
The umbra is the darkest portion of a shadow.
The prenumbra is the lighter edges of a shadow.
The antumbra is the shadow created at the end of the umbra
