Classical Electrodynamics and Quantization — •Gunnar Kreisel — Gottfried Wilhelm Leibniz Universität

Quantization means that electromagnetic radiation emerges in whole numbered multiples of a constant fundamental quantum. As early as 1900, Max Planck described quantization as an effect resulting from the conditions of electromagnetic radiation that is emitted in a cavity in thermodynamic equilibrium. Seemingly without connection to PLANCK*S assumption, electric elementary charge was determined by using three fundamental laws in 1911 (E.g. Faraday*s law of electrolysis). In classical electrodynamics it was not basically discussed that both the nature of quantization and that of electric elementary charge are each consequences of the special properties of electromagnetic waves. The source of electromagnetic waves (radiation) is the oscillation of an electric charge. Based on the constitution of the oscillating charge the quantization of electromagnetic radiation is but not a trivial consequence simply because the properties of electromagnetic waves are not only fixed by the composition of the oscillating charge but e.g. by frequency, too. This fact along with other relevant properties of electromagnetic waves will be discussed in a wider sense. Within this, an important aspect are the epistemological conclusions of the consequences of the special properties of electromagnetic waves.
