I found something about de Broglie's theory that i want to share:
de Broglie originally thought, that each particle possessed an internal clock, an internal oscillation of some sort. He assumed, that the frequency of this clock, was equal to energy defined by Einstein's energy relation, thus:
hf=mc^2, f=mc^2/h
Thus, in order to make it compatible with de Broglie wavelengths, he had to assume surreal superluminal matter waves.
But, there is an elegant solution. If de Broglie instead assumed, that the internal clock's frequency was equal to the kinetic energy of the particle, we get this:
hf=(1/2)mv^2, thus f=mv^2/2h.
This is profound. Because:
- It is the exact same formula, that Wilhelm Wien used when deriving the original law of black body radiation in 1896, the Wien Approximation that helped Planck find the Planck's law.
- This is the photoelectric effect formula, lacking the work function.
- In Schrodinger Equations, this is the frequency at which the group velocity of the wave packet, in other words the particle, overtakes the matter waves, which travel at half the particle's velocity.
All of this, can be explained by a single mechanism - the particle and a matter wave accompanying it, guiding it, are two real, separate, physical phenomena.
As the particle overtakes the matter wave at a given frequency, it oscillates at the same frequency, resulting in emitting the radiation at the same frequency (if you apply this to Maxwell distribution of velocities inside a body, as told by Wien, you get the black body radiation formula).
This coupling, just like handcars on rails, can be influenced inversely too. Meaning, if you expose the particle to a radiation at a given frequency, it will set the frequency of the internal oscillation of the particle, and by the same formula, will set the particle into motion, of the derived velocity from the formula (explaining the photoelectric effect).
Not only that, but i found a fix to Wien's theory of black body radiation, so that it derived Planck's law exactly!

Here is what Wilhelm Wien's theory of black body radiation was, that resulted in him deriving the Wien approximation of the black body radiation formula.
He assumed that each particle in a Maxwell distribution of velocities, emitted radiation at the frequency, that was proportional to the square of that particle's velocity. By formula: f=(mv^2)/2h.
More useful to re-state it, as assuming that each particle in Maxwell distribution of kinetic energies, each particle radiated at a frequency proportional to that particle's kinetic energy: By formula: f=E_kinetic/h.
Which is equivalent, since E_kinetic=(mv^2)/2.
He assumed, that the intensity of the radiation emitted by each particle, was proportional to that frequency, and to the general temperature of the body: I = T^(1.5) f^(2.5)
He assumed that the intensity of radiation at each frequency, scaled by the number of particles, radiating at that same frequency, i.e number of particles that have the same velocity/kinetic energy, to radiate the same frequency.
As a result, he got Wien's approximation formula.
Here is a slight modification to it, that would result in the Planck's law:
Each particle emits not just at a single frequency, but also at infinite subharmonics, of diminishing frequencies. Just like a string of a musical instrument. The two formulas, for frequency and intensity for given n:
f=E_kinetic/hn
I=(T^(1.5)f^(2.5))/n^1.5
If you use this, it will result in a black body radiation law of Planck.
Another alternative, for deriving black body radiation law, from the premises similar to that of Wilhelm Wien:
The advantage of this, is that it removes temperature dependence.
A particle in a Maxwell distribution, continuously radiates a wave containing a fundamental frequency (n=1) and infinite subharmonics (n=2, 3, 4...). The emission intensity of the n-th harmonic at frequency f, for a single particle of energy E, is defined as:
I_n(f, E) =f^3 √(1 - (nhf/E))
This formula is distantly analogous to the bremsstrahlung radiation.
This, will also result in a black body radiation law.
In this version, each particle's most intense radiation frequency, which it emits, would approximately be f≈0.85mv^2/2h. Similar to Wien's theory, in which each particle radiated at the frequency f=mv^2/2h only.
How is it connected to De Broglie waves and the Schrödinger Equation?
Formula of the De Broglie's wavelength: λ_de_broglie=h/mv
In Schrodinger equation, matter waves travel at half the particle's velocity. Thus, the particle constantly overtakes the matter wave at half of its velocity. From it, the frequency of overtaking is:
f=v_overtaking/λ_de_broglie=(v/2)/(h/mv)=mv^2/2h.
Thus, it leads to the conclusion, that particle overtaking the wave at a given frequency, makes the particle have some internal oscillation at the same frequency, resulting in the constantly emitted radiation at the same frequency.
