Reconciliation of the Wave-Particle Duality and Formulation of the Photoelectric Equation from the Laws of Capacitance Lane M Davis ©2014 seattle.truth@gmail.com Abstract When the Planck constant was applied to the photoelectric equation in 1905, it introduced the greatest paradox of modern physics: the waveparticle duality of light. If the energy of a photon can be explained to arise from its wave nature, then the particle regime becomes obsolete and irrelevant. By modeling the photon’s wave as a capacitor, the wave nature of light becomes sufficient to explain and calculate the energy of the photon, as well as all other aspects of behavior, thereby reconciling the wave-particle duality. Math is the language of the universe. All governing laws are related in ways that should make logical and mathematical sense. This author proposes that if a constant has to be injected into an equation as a fudgefactor, it is not necessarily an unsolvable mystery, but that the reason the constant is in the equation is just not yet understood. Planck’s constant is empirically measured to produce incredibly accurate results in equations where it is injected, but there has never been postulated a coherent logical reason why the constant is in the equations – until now.

In a classical wave, the energy associated with the wave correlates to its amplitude[17]. With a light wave, it seemed like the amplitude was irrelevant, as it Prior to 1905, the photoelectric effect did not matter how much light was was a baffling mystery[3] – deeply tied shined onto metal – larger waveto what was dubbed the ultraviolet lengths would not eject any electrons catastrophe[10].

In 1900, by observing a pattern in blackbody radiation and making the then-outlandish assumption that energy came in discrete packets, Max Planck was able to give a formula which described the observed distribution of energy among the emitted wavelengths[3], which led him to formulate the Planck Radiation formula[19], which introduced a new constant, h. Planck did not realize the applications for his constant and did not truly believe in the discrete nature of energy; he believed it to be an artifact of a flawed mathematical model[3]. Everything changed in 1905. With his revolutionary idea of a fixed velocity for light, Einstein was able to give every wavelength a corresponding frequency[23]. He then took Planck’s newly discovered constant, and injected it ad-hoc[4] into a very simple equation: E = hf . Einstein did not understand how, or why[1], but when he multiplied Planck’s constant by the frequency of light, it produced the experimentally proven energy levels for all known wavelengths. He could not explain why Planck’s constant is the conversion factor between the frequency of light and its energy[1], but it undoubtedly worked. Quantum optics was born. The idea that the energy of a photon came from its frequency introduced the wave-particle duality[25]. The energy in this regime came from the wave’s frequency, instead of the wave’s amplitude, which gave the photon a particle nature even though it behaved like a wave in diffraction experiments[25]. This ad-hoc solution was heralded as one of the biggest breakthroughs of the century, and Einstein eventually won his only Nobel prize for this simple equation, despite the fact that it could not be rationalized or explained by anyone why Planck’s constant was in the equation in the first place[5]. Planck vehemently disagreed with Einstein’s conclusion that energy was inherently quantized or particle in nature, and saw Einstein’s formulation as “nothing more than a mathematical trick”[3]. This author contends that Planck was right all along – that the particle nature of the wave is just a mathematical artifact that was hitherto misunderstood, and that there is a logical reason why Planck’s constant is a conversion factor between the frequency of a photon and its energy, and that the photoelectric equation can be formulated logically by the application of commonly known laws. Capacitance of the Photon Fig. (1) The first step to achieving this is to model the photon as a parallel plate capacitor. Undoubtedly, the photon has no net charge, but carries a positive and negative charge at different times as it propagates through space[13][28]. The photon also displays another characteristic inherent to capacitors – it is essentially connected to positive and negative terminals; the atom emitting energy (positive lead) and the atom absorbing energy (negative lead). Despite these two similarities, it may 2 Lane M Davis ©2014 all rights reserved seem illogical that this fundamental aspect of nature could or should be compared to a capacitor. At face value, a photon does not seem to exhibit any of the characteristics of a set of plates. This misunderstanding is because the photon is usually visualized from the frame of reference of an outside observer, where it propagates through both time and space. It is necessary to visualize what the photon experiences, not what the outside observer experiences from the photon. From the frame of reference of the photon, many things change, and the system can then be examined electrostatically. For instance, the photon is traveling at the speed of light, therefore because of the implications of special relativity and the Lorentz transformation, the photon does not experience time[22]. Time does not exist for the photon. Because there is no time, this means the photon occupies both the positive and negative states simultaneously. In reality it is alternating between the positive and negative charge sinusoidally through spacetime, as an outside observer would see (if one could hypothetically observe a photon without interfering with it in some way), but from the frame of reference of the photon there is no time, only space, so it is indeed both positively and negatively charged at the same time. This fits the first aspect of a plate capacitor; having a charge differential. traveling in a line. Fig. (2) Is a horrible representation of reality, although it does display some of the physical attributes and is an easy model for the Luddite stuck in the Newtonian regime to digest. The uncertainty principle tells us this model is not accurate; that a particle has neither a perfectly defined history nor a perfectly defined location[24]. Single slit Fraunhofer diffraction shows that a photon does indeed have a width, as when the slit is closed tighter than one wavelength, the wave interferes with itself, and produces strange but mathematically logical results[16]. Therefore, the photon not only has a wavelength, but it also has a width. It also has a distance between the positive and negative components (Fig. 2). The distance between the positive and negative charge peaks of the sine wave is half a wavelength. When the photon is viewed as frozen in time, it does display the characteristics of a plate capacitor; two oppositely charged surfaces both with a length, a width, and separated by a distance. It must be noted that the photon is positive for half of its length, and negative for half of its length (Fig. 2); so the length of each plate is half a wavelength. It must also be noted that the photon does not become even semi-localized until it interacts with a particle[26]. From emission, it travels through spacetime as nothing more than a superposition of possibilities, propagating according Fig. (2) to Schrödinger’s wave equation[21] until the wavefunction collapses upon absorption, where these three dimensional properties take shape. Knowing the three properties of length, width, separating distance, and that the dielectric in this case is spacetime itself[29], with a vacuum permittivity of ε0 , we can calculate for the Another misconception is that a capacitance of the photon using the photon is a one dimensional particle standard equation for an ideal paral3 Lane M Davis ©2014 all rights reserved tion, and plugging in e for the charge Q, produces: lel plate capacitor with the vacuum as the dielectric[18]. e2 (4) 2ε0 λ It would suffice to just solve for Plugging in 21 λ for length, λ for E to calculate the correct energy lev1 width, and 2 λ for distance, and then els for the entire electromagnetic speccanceling, we produce: trum, but something very interesting happens when we put this equation in C = ε0 λ (2) terms of frequency, which is possible because f = λc [23].

Q2 E= (3) 2C C= ε0 A D Eα = (1) Energy of the Photon Conclusion In this case, the charge (Q) is the elementary charge (e), which is the maximum charge of the photon during its sinusoidal peaks. It must be emphasized that the photon has no physical properties until it interacts with another particle[26]. We are not trying to solve for the energy of a photon in free space. Such a photon cannot be measured, therefor according to the Copenhagen Interpretation, it does not truly exist[6]. We are solving for the energy of a photon that is interacting with an electron (or more accurately, the electron’s virtual photon[20]) through the action of electromagnetic coupling[12]. Therefore we must take into account the strength of the coupling, which is the fine structure constant, α[12]. We are solving for the energy of the coupled photon, so we must place α into the equation to solve for the coupled energy. Inserting Eq. (2) into Eq. (3), placing α on the energy side of the equa- Nature is written with mathematics. Math is all nature knows[8]. When equations work out to produce accurate predictions, they describe something about nature. It is up to us to sit down, listen, and try to figure out what the math is saying; to decipher what we learn and put it into the syntax of human language. These equations are telling us that the photon is an ideal capacitor. When physics equations work, it is never purely coincidence. This is the reason why string theory took off in 1970[9], when the equations produced accurate results by modeling particles as reverberations on a string. In the case of a photon modeled as a plate capacitor, not only does the math work to produce accurate results for every known wavelength, but deep down at a fundamental level a photon makes logical sense as a capacitor. A capacitor 4 Lane M Davis ©2014 all rights reserved stores energy through a charge differential, and that’s exactly what a photon does, with spacetime as the dielectric, and connected to two atoms which act as the positive and negative lead. In this regime it becomes clear what gives rise to Planck’s constant in the famous photoelectric equation. It is not a fundamental property of nature, as Planck ardently argued[3] – it is an aggregate constant, birthed by the relationship of capacitance and energy and the uncertain location of the photon, in conjunction with relativity, the permittivity of free space, and the strength of electromagnetic coupling. This reconciles the waveparticle duality[25], as now we can see that the energy of the photon is not caused by its frequency, or its particle nature, it is simply caused by its capacitance, and its corresponding voltage (V = Q C [14], where Q is the elementary charge) which is determined by its wavelength. The smaller the wavelength, the smaller the capacitance, which means a larger voltage, and therefore more energy in the system. The voltage of the photon is the amplitude in this wave, because it is an electrical system. The energy of a photon does relate to the wave’s amplitude, just in an unsuspected way, because it is an electrical wave, and must be thought of as such. The energy of the photon is caused by its wave nature after all, just as the probability of its location is caused by its wave nature. This is the explanation that Planck knew in his heart must exist, although he was unable to find it. This author concludes that what is considered a particle after the wavefunction collapses is nothing more than a semi-localized smearedout wavepacket that imparts its energy through the voltage of the three dimensional nature of the wave, as it cannot be totally localized but has a constant charge differential due to the elemen- tary charge. Bohr’s rule of complementarity therefore does not apply to the Copenhagen interpretation regarding the wave-particle duality[2]. Furthermore, the quantized values of energy that we observe for the entire spectrum of light is not due to some intrinsic particle-side-of-the-duality of the photon, it is simply due to the conservation of energy and the fact that each energy level of the atom must be occupied by what can be modeled as a standing wave[27]. During quantum transition, the electron must jump up or down to another standing wave. The photon itself can occupy any energy imparted to it, and therefore any wavelength, but because the energy levels themselves are determined by energy levels where standing waves of the electron can occur, only certain energy levels of light can be admitted. Because energy is conserved, these photons contain the exact energy of the atom that emitted them, and are only able to be absorbed by atoms which require the exact amount of energy contained in them, giving rise to a totally quantized world. Again, Planck was right[3], and there is nothing inherently choppy or discrete about the energy levels of the photon. It is because they can only take the energy given to them by the captured electron, which must occupy a standing wave, which only happens at discrete levels. Energy is quantized by proxy. However, there are many questions left to be answered. This author does not understand why the fine structure constant is the value it is for coupling. According to QED, photons do not interact directly with electrons, they interact with virtual photons given off by electrons[20]. Therefore, because photons are shown to be three dimensional capacitors when frozen in time, and photons interact with electrons through virtual photons, the virtual photons probably also exhibit this 5 Lane M Davis ©2014 all rights reserved kind of capacitorial behavior – this author suspects that the value might have something to do with capacitors being wired in series, which lowers the capacitance of the system. This may or may not be the case. This author also suspects that this wave-capacitor regime can explain why Planck’s constant arises in all of the equations regarding electromagnetic and quantum interactions. Although reconciling the wave- particle duality has its merits, determining why the fine structure constant has the value it does through logical analysis is thought to be the equivalent of the Holy Grail of modern physics[7]. Possibly these new insights on the nature of light can help illuminate that path. This author feels that all the fundamental constants are related in ways which we are only just beginning to understand. References [1] Salama Abdelhady.
