What are the different types of shadows?
A point source of light casts only a simple shadow, called an “umbra”. For a non-point or “extended” source of light, the shadow is divided into the umbra, penumbra, and antumbra. The wider the light source, the more blurred the shadow becomes. If two penumbras overlap, the shadows appear to attract and merge.
