Using de Broglie wavelength we can explain the concept of how the electrons moved around in fixed circular orbits by saying those are the standing waves in which the electron moves around the nucleus in resonant conditions.
However, from my understanding, it is still a concept that is used in modern quantum mechanics. So, in what way does the way the postulate is used to explain phenomena in modern quantum differ from how it was used to explain the Bohr atom?
I'm particularly interested in how the application of the de Broglie postulated as an explanation of the circular orbits in which the electrons move was found to be wrong.
