Shadows Learn Definition Properties And Facts Umbra (a) and penumbra (b) the umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. assuming no diffraction, for a collimated beam (such as a point source) of light, only the umbra is cast. these names are most often used for the shadows cast by celestial bodies.
