The convergent light from the source can be considered as a collection of many plane waves propagating in a specified set of directions and superimposed to form the incident illumination.
What a collection of players.
The infrared spectra of proto-planetary nebulae display broad emission plateaus at 8 and 12 μm, which probably originate from a collection of different in-plane and out-of-plane bending modes of aliphatic groups attached to aromatic rings (Kwok et al., 2001).

The tessellation (a tessellation or tiling) of the plane is a collection of figures that fills the plane with no overlaps and no gaps) induced by the set of CVs is optimal if all data within one cell indeed belong to the same class.
Whenever a Julia set is not connected, then it must be simply a collection of dust on the plane, with the same general structure as the Cantor set.
