Abstract
The article mainly discusses the question in what sense the term «wave» is used when teaching general physics at a technical university. For this purpose, the texts of the main physics textbooks for technical universities, as well as several other books, are analyzed. The analysis is based on the concept of «physical parts of speech» proposed by two of the authors in previous works. It is shown that the term «wave» is used in textbooks in three senses, and it is not always clear from the context which of the three is meant by the authors. First, the term
«wave» is used to refer to a physical phenomenon, that is, vibrations in an elastic medium or at the interface of media (waves on the surface of water), which are accompanied by energy transfer without noticeable transfer of matter. This includes sound waves, seismic waves, etc. Secondly, the word «wave» means a model (for example, «monochromatic wave», «plane wave», «traveling wave», «standing wave»). This includes electromagnetic waves: this is evident, if only because they do not require any environment for their distribution. Finally, third, the word «wave» means a basic physical concept: for example, the de Broglie wave, the probability wave, the wave properties of electromagnetic radiation. We believe that when studying the corresponding section in the course of general physics in at a technical university, it is necessary to emphasize every time what, in fact, is being discussed. This will make teaching physics to students more effective and bring it closer to the physical reality around them.
