Introduction,atoms and their interactions with one another and with electric and magnetic fields. Atoms are made up of positively charged nuclei and negatively charged electrons. The electromagnetic forces through which these particles interact are well known in classical physics.

In the 19th century, the physical nature of these waves came to light: they are electromagnetic waves, described by Maxwell’s equations. They are characterised by the field vectors . and . of the electric and the magnetic field and exhibit a periodicity with the frequency ..

Digitalisierung im Recruiting: Chatbots are usually the outermost or valence electrons. If we now turn to x-ray spectra, we shall be concerned with the energy states of electrons in inner shells. We shall see, however, that x-ray spectra can for the most part be treated as one-electron spectra, although they belong to many-electron atoms.

,Das ?rgernis: ?Der Druck macht fertig“,In the two preceding chapters it was shown that light, electrons and other elementary particles can have both wave and particle characteristics. In this chapter we will examine more closely how the wave properties of matter can be understood and described mathematically.
