In many respects this is a more natural form for the theorem: the monochromatic subspace 'looks like' the original space.
In other words, each monochromatic connected component must be a single vertex.
This is because monochromatic photons must have positive energy and hence also positive frequency.
The obstructed discharge in low operating gas pressure produces a monochromatic beam owing to little interactions of electrons with neutrals.
These are applicable to atoms subjected to monochromatic light of high intensity.
For propagating monochromatic sound waves these are defined as follows.
Such a poor resolution in the ver tical direction is actually the main drawback of using the scheme presented to per form monochromatic imaging.
Also, monochromatic connected components are cliques of order t, corresponding to affine lines.
