Abstract
On the theory of emission and absorption of electromagnetic radiation — an argument
A more complete than usual use of the argument of the identity of photons is suggested for the teaching of radiation processes at the elementary level. The argument uses the concept of ‘observability’, known from system theory for estimating in the quantum-mechanical and statistical contexts, of the probability of occurrence of a casual process. The introductory discussion in Section 2 explains the reasonability of learning optoelectronics in the device-applicative, physical and system-theoretic aspects, with some emphasis associated with the research interests and pedagogical views of the author.
