It is studied in this paper that, with light being reflected on two medium dividing surfaces, half-wave loss, a sudden change in π place at reflecting point, happens to reflection light, which turns out to be its quantum nature. The theory of wave-particle duality is applied to this research in the way wave function is described.
The simplest but deepest questions of the philosophy of quantum mechanics are these: Are quantum systems waves, or are they particles? Are they both or are they neither? When light bounces an electron out of the surface of an alkali metal it behaves like a particle. Light carries momentum but also a punch. Just as there is no such thing as half a punch, so there is no such thing as half a quantum of light. On the other hand, the shadow formed on a screen by an object has soft edges, edges which get softer as the object is moved away from the screen. Light exhibits the phenomena of diffraction and interference and so is wavelike. This dual behaviour of light, and indeed of matter itself, is called wave-particle duality. The wave nature of a quantum system is reflected in wave mechanics which assigns a wave-function to the system. But the dual nature of light was noticed before Schrodinger developed the wave-mechanical formalism in 1926. In fact, it goes back at least as far as Einsteins explanation of the photoelectric effect in 1905. Wave-particle duality is not something that arises within the quantum mechanical formalism. It is something which is expressed within it, and is something which is best discussed in terms of the paradoxes that quantum experiments force upon physics. In fact, the simplest and most immediately disturbing of the quantummechanical paradoxes arise out of wave-particle duality. We take the two-slit experiment and the delayed-choice experiment as examples.
Abstract When a light wave is reflected at the interface between two semi-infinite media, the relative phase between the reflected and incident amplitudes is a fundamental optical effect. Another fundamental phase relation arises in a symmetric beam splitter between its reflection and transmission amplitudes. Both effects originate from the phase structure of wave scattering, although their underlying connection is not always clearly understood. As a pedagogical investigation, this paper systematically analyzes these phase relations using simple one-dimensional potential models in quantum mechanics and provides intuitive physical explanations. For a symmetric square barrier, the reflected and transmitted amplitudes necessarily differ in phase by ±π/2, with the reflection phase referenced at the interface on the incident side and the transmission phase referenced at the interface on the exit side. The result is further extended to general symmetric barriers, for which the detailed form of the barrier determines only whether the phase difference is +π/2 or -π/2. The role of this phase structure in the second-order interference of two identical particles is then examined. Through this sequence of analysis, half-wave loss at a reflecting interface, the phase relation in a symmetric beam splitter, and multiparticle quantum interference are incorporated into a unified wave-scattering framework. This treatment provides a useful pedagogical reference for related topics in quantum mechanics and optics courses.
Quantum mechanics is one of basics theories of modern physics, and it is also a theory established with some debates of assumptions. However, in the teaching process, if the assumption of wave-particle duality is directly given, it will be particularly difficult for students to understand. Therefore, based on the teaching practice and previous research, we assume that light corresponds to a kind of real particle starting from the classical electromagnetic theory, according to the description methods of wave optics and geometric optics, and the form of functional equations. Subsequently, employing Planck's quantum conditions, we discuss the connection between the wave nature and particle nature of light. And then the Planck-Einstein relation and the de Broglie relationship are derived, which reflect the wave-particle duality of light and real particle.
The wave-particle duality is a fundamental property of the nature. At the same time, it is one of the greatest mysteries of modern physics. This gave rise to a whole direction in quantum physics - the interpretation of quantum mechanics. The Wiener experiments demonstrating the wave-particle duality of light are discussed. It is shown that almost all interpretations of quantum mechanics allow explaining the double-slit experiments, but are powerless to explain the Wiener experiments. The reason of the paradox, associated with the wave-particle duality is analyzed. The quantum theory consists of two independent parts: (i) the dynamic equations describing the behavior of a quantum object (for example, the Schrodinger or Maxwell equations), and (ii) the Born’s rule, the relation between the wave function and the probability of finding the particle at a given point. It is shown that precisely the Born’s rule results in paradox in explaining the wave-particle duality. In order to eliminate this paradox, we propose a new rational interpretation of the wave-particle duality and associated new rule, connecting the corpuscular and wave properties of quantum objects. It is shown that this new rational interpretation of the wave-particle duality allows using the classic images of particle and wave in explaining the quantum mechanical and optical phenomena, does not result in paradox in explaining the doubleslit experiments and Wiener experiments, and does not contradict to the modern quantum mechanical concepts. It is shown that the Born’s rule follows immediately from proposed new rules as an approximation.
In the context of this book, composed of a series of quantum and artistic reflections, the concept of mirroring plays a unique role. Quantum mirroring, viewed through an artistic lens, carries a poetic yet complex simplicity. Like many quantum phenomena, it reignites curiosity about how we as humans engage with the world. The phenomenon occurs when an electron or photon sees itself reflected in the mirror-like surface of mercury. 1 The self-awareness of a submolecular particle continues the theme of the dual-slit experiment. In this case, we encounter a form of narcissism at the quantum level. We’ve already touched on the flâneur, but now we turn to the electron or photon, which, once observed, changes from a wave to a particle. However, when it appears as a reflection in mercury, it creates a constant oscillation between wave and particle duality.
What quantum theory has revealed about the nature of reality has remained hidden in plain sight for almost one-hundred years because what quantum theory has revealed about the nature of reality cannot be comprehended in the context of the materialist model and conception of reality in which science presently operates, which materialist model places physical reality at the center of reality and Consciousness at the periphery, as a secondary or derivative reality. What this work will demonstrate, by explaining the heretofore inexplicable basis of the phenomena that lie at the heart of quantum theory, is that it is Consciousness rather than physical reality that lies at the center of reality, and that it is physical reality rather than Consciousness that is a secondary or derivative reality. Specifically, wave-particle duality, quantum uncertainty, quantum non-locality, the probabilistic nature of the wavefunction, and the collapse of the wavefunction, will all be shown to be phenomena that have as their basis the way in which the fundamental Reality of Consciousness, through relation to Itself, creates what it apprehends as physical reality.One of the most important things the phenomena that lie at the heart of quantum theory will be shown to reveal about the nature of reality is that the nature of physical reality is like that of a reflection, and like a reflection, physical reality is able to obscure from view what is actually there, as long as it is mistaken for what is actually there. Thus, in revealing the reflection-like nature of physical reality, the phenomena that lie at the heart of quantum theory indirectly reveal that what is actually there, underlying the reflection that is physical reality, is the non-physical, non-experiential Reality of Consciousness that is, through relation to Itself, both creating and apprehending experiential reality in general and physical reality in particular. Ultimately, understanding the reflection-like nature of physical reality should make it possible for Individuals to understand that what actually Exists directly where they are, where their physical bodies appear to be, is not different in Nature than what actually Exists everywhere else as well, where the rest of physical reality appears to be, thereby disabusing them of the notion that what they are is a physical reality, while at the same time revealing to them their true Nature as Consciousness, which, through relation to that which is also Consciousness, creates what they, as Individual points of Consciousness, apprehend as experiential reality in general and physical reality in particular.Part II of this series of three articles includes: 2.
