Frequency And Wave Number Viewed Through Systemic Functional Linguistics

Penrose (2004: 500):

Detailed experimental issues are not things that I can go into here, but the essential point that emerges from a vast amount of experimental evidence is that there is a direct association between frequency and energy, and a corresponding association between wave number (the reciprocal of wavelength) and momentum; moreover, these associations appear to be universal, in all phenomena.

From the perspective of Systemic Functional Linguistic Theory, the frequency of light is the number of photons per interval of time, and the wave number of light is the number of photons per interval of space. The number of photons per time unit is associated with energy, and the number of photons per space unit is associated with momentum. (The wave quantifies light as potential, with each wave crest as the most probable location of an actual particle.)
