///. Light of a fixed frequency "interacts" (is emitted and
absorbed) in discrete photons - parcels having definite energy-momentum.
The mistake often made is to try to assign a "length" to a photon.
Fourier tells us that this is impossible, since the photon has, by
definition, a definite frequency. As is usual in QM, care must be taken
not to mix incompatible attributes (such as position and momentum).
