Essay from the year 2019 in the subject Physics - Theoretical Physics, grade: 2.00, language: English, abstract: It is posited that the frequency of electromagnetic radiation may be quantised and two methods are derived which permit the calculation of the magnitude, delta, of the quantisation. The work does not establish the existence of frequency quantisation and the two methods derived may be described by the oxymoron, systematically arbitrary. Both methods rely upon the Fidler diagram. The first method employs the superposition of a fractal path on the diagram and gives, delta = (V)/(sqrt 2)^(n-1), where n is a disposable odd integer, and (V) is the Planck circular frequency. The second method involves the tiling of the diagram by a succession of self-similar tiles which are progressively-reducing versions of the diagram itself. In this case, delta = (V)/ (sqrt 2)^(2(n-1)), where n is any integer. Erratum: The relevant Planck quantities on p16 should read: Planck length, (L) = 4.05134*10^-35 m. Planck circular frequency, (V) = 7.399825*10^42 Hz. Planck spectroscopic wave number, (Z) = 2.468316*10^34 m^-1. Planck specific energy, (S) = 12.1026*10^43 J/m. Planck specific energy intensity, (I) = 2.987308*10^78 J/m^2. Planck specific energy density, (D) = 7.373629*10^112 J/m^3. The work also shows that the Fidler diagram is the two-dimensional projection of a three-dimensional surface.
