Since these properties could only be explained by the wave theory, the particle theory fell out of favor. Because the same prefixes are used repeatedly. such as the automotive. Another characteristic of waves is the frequency, f. A mower bolt is torqued to 65. what is the length of the wrench? The de Broglie-Schrodinger wave fields were not to be interpreted as a mathematical description of how an event actually takes place in time and space, though, of course, they have reference to such an event.
