ABSTRACT: The wavelet envisioned by Huygen’s in diffraction phenomenon is re-interpreted as a Polarized Wave (PW) after passing through slit/hole/or biaxial crystals which removed the electric field component from the Electromagnetic Radiation (EM-R), the resulted wave is what is known as the Conical Diffraction (CD) beam, the PW is originated from the Circular Magnetic Field (CMF) produced by accelerated electrons, integrated with the Electric Field (EF) during the Flip-Flop (F-F) mechanism producing EM-R; hence the passing of light through a single hole/slit/biaxial crystals, resulted in a PW which reproduced as rings on the monitor screen in single wave diffraction, while the interference of two such PW in double slits experiment, produced constructive or destructive interference forming patches on the monitor screen; and the perceived electron diffraction is an enter of two CMF from an accelerated electron into two slits then emerged to interfere constructively or destructively, and appears as patches, in addition to the electron which entered and emerged from the slit with the intense CMF, the paper finally derived the origin of Planck’ constant (h) for the second time; the logical interpretation of double slits diffraction will restore the common sense in the physical world, distorted by the pilot wave. In order to achieve this, the actual mechanisms involved in the Wheeler's delayed-choice experiment and Einstein's spooky-action-at-a-distance are uncovered from the quantum formalism. the photon with the detectorâs probe will result in the disappearance of the earlier IRSM. appear as a proof for the observed particle behavior at the respective slits. Hypothesis(1): Once the notion of Euclidean space is given up and the complex vector space is accepted as the actual space. This type of experiment was first performed, using light, by Thomas Young in 1801, as a demonstration of the wave behavior of light. the `spooky-action-at-a-distance', another mystery regarding the entangled quantum (0) are constants of integration corresponding, is the heart of quantum formalism; where, Ë, is a linear superposition of all the eigenstates of, appears, say at some position eigen value, ) and the corresponding instantaneous eigen mode is, be the position operator with eigenstates, is subjected to the conservation laws and the inner-product interaction is given b, and is associated with a projection operator, , to the head surface passing through the center-of-mass of the coin and let, will be either parallel or anti-parallel to, is replaced by electronâs spin magnetic axis and, should be ether parallel or anti-parallel to, as a preferred direction attached to it and (ii) the gravitational force in the ï¬at. .

Although this phenomenon has been Phys. in the region where the detector probe interacts with the particle in the vicinity of the slit. Without diffraction and interference, the light would simply make two lines on the screen. The slit experiment was first performed in 1801 by Thomas Young. Also, an actual. without modifying the force equation, letâs consider the case where the space is complex and it itself splits into two. Young’s double-slit experiment – problems and solutions. Young’s double-slit experiment gave definitive proof of the wave character of light. The next photon appears at the source along with its IRSM whose phase will be diï¬erent from the previous photon. During the year 1801, Thomas Young carried out an experiment where the wave and particle nature of light and matter were demonstrated. Thomas Young's double slit experiment was extremely important in the area of wave theory. Then the most crucial property of S seems to be: and his introduction of the wave-particle duality into physics ill 1909. either due absorption or scattering at the detector screen, then the entire IRSM disappears leaving the photon to, contribute a point in the interaction region. © 2008-2020 ResearchGate GmbH. dual-pinholes but just after the grid so that the images of the pinholes 1 and 2 fall on the photon-detectors, By blocking the pinhole-2 (pinhole-1), the light intensit.

Chapter 4 The Two Slit Experiment 30 First perform this experiment with one of the slits open, the other closed. in the Young's double-slit experiment which is known to be demonstrated with photons, electrons, neutrons, and atoms, the dual Young's Double Slit Experiment - theory. The entre of EM-R in single slit, then changed into PW, produced the same shape of circular wave on the screen, ... Based on force carrier, the photon was thought to mediate the electromagnetic interaction, the massive gauge bosons called the W and Z bosons mediate weak force and gluons mediate the interaction of color charges in the strong interaction [43]. inner-product interaction and also due to the equality of classical and quantum mec. The Young's double-slit experiment, the Wheeler's delayed choice experiment and the Afshar's experiment are unambiguously explained at a single quantum level. and it interacts with the excited dual-mode. a double- slit arrangement (left). 110, 210403 (2013)'', at the level of individual quantum events. There is no distinction between the software and the hardware in Natureâs programming. occurred on the screen is lost and two clump patterns, one at each telescope, are formed. The experiment serves as the , when either pinhole-1 or pinhole-2 is kept open, respectively; here. single entity is termed as non-duality. C60 are large, massive, and appealing objects for which it is quantum mechanics itself is not a probabilistic theory, Bornâs rule by showing it to be equal to the experimentally observed relative frequencies. these two natures are treated as complemen, using the quantum formalism, no physical mec. This viewpoint is proved by deriving the Born's rule by showing it to be equal to the experimentally observed relative frequencies. Consider its Hamiltonian. The probabilities in quantum mechanics arise only for the observer's perspective due to the nature of doing experiments but they do not exist in Nature. The resultant intensity distribution is then a curve which peaks behind the position of the open slit, much like the curve obtained in the experiment using bullets. All rights reserved.

In fact, this inner-product interaction can be found easily within the quantum formalism itself. exists simultaneously in all possible positions before the measurement. Now, let us consider the energy eigenstate, The particle will be present at some particular eigenstates, the inner-product interaction is responsible for the perception of the space to b. arbitrary potential and will be reported elsewhere. is naturally contained in the non-dualistic interpretation. Consider the case of single photons shot at the pinholes 1 and 2 so that any photon is ï¬red only after the registration, of the previous photon by any one of the photon-detectors. A model of crystal is suggested, in which atoms are bonded by the Spinning Magnetic Force (F_S) created by the Nucleus Spinning Magnetic Field (NSMF); thus the passing of x-rays through the crystal lattice, having smaller width compared to x-ray wavelength, polarized the x-rays, which is part of Electromagnetic Radiation (EM-R) spectrum, by removing it’s electric field component and transformed the residual into Polarized Wave (PW), or what is known as Conical Diffraction (CD) beam; hence the emergence of PW from crystal is synonymous to the passing of Circular Magnetic Field (CMF) surrounded an electron through such crystal; hence both PW and CMF interacts with the NSMF producing the Glowing Spot-PW (GS-PW) for x-ray diffraction and Glowing Spot-CMF (GS-CMF) for an electron diffraction, appeared on the monitor screen as dots/rings or reflected as dots patterns; the Kikuchi lines are interpreted as resulted from the interaction of the CMF with the Nucleus Spinning Magnetic Lines of Force (NSMLF), producing the G-NSMLF; thus the interpretation of diffraction as an interaction between wave and matter, is extended to an interaction among intense magnetic fields, and this is the conclusion of this final paper, aimed among others at restoring the common sense in the physical world, removed by pilot wave. material objects have an intimate connection with the space-time in such a w. the Cosmic speed limit in any inertial frame of reference. frequency of occurrence arises due to the nature of doing experiment. Feynmann, TheFeynmanLecturesonPhysics, Vol. 1 show that Robert Andrews Millikan, in common with almost all physicists at the time, rejected Einstein's light-quantum hypothesis as an interpretation of his photoelectric-effect experiments of 1915. Layout of the apparatus. G. Auletta, Foundations and Interpretation of Quantum Mechanics, (World Scientific, 2001). still survives until the detection of the electron. quantum character of the famous double-slit experiment can be best originated and remains unaltered as long as the particle sustains with the same momentum, i.e., âorigin remains, unaltered as long as the momentum of the particle gets unaï¬ectedâ - is an important property of the complex vector, The ï¬nal boundary condition depends on where the particle will end up and need not b, (both boundary conditions are ï¬xed for the case of b, changing interaction, then the earlier IRSM disappears completely and a new IRSM corresponding to new momentum. A monochromatic light source is incident on the first screen which contains a slit . position-momentum commutation relation remains unaï¬ected, i.e., to each other though they give rise to the same set of position eigenv, Here, itâs worth mentioning that a given quan. Monochromatic light, light consisting of one color, is split using two slits … This paper suggested a mechanism for Electromagnetic Radiation (EM-R); the mechanism is based on the Flip-Flop (F-F) of combined Circular Magnetic Field (CMF) and Electric Field (EF) produced by energetic charged particles, the action released the EM-R; while as the F-F generates EM-R, it is also achieved within specific Flipping Time (tF), the inverse of which is the Flipping Frequency (fF), the model is compared with Maxwell’s two transformations to elaborate differences and characteristics, hence when EM-R is better understood, that will reflects on the physical world and related human ideas and philosophies. basis for a discussion of several quantum concepts such as coherence, The double-slit experiment is considered revolutionary as it was our first outright hint that there is more to matter, light and energy than first suspected. can be visualized as the best physical representation for the Copenhagen interpretation. diation Based: With Atomic Model" at: (http://fundamentaljournals.org/ijfps/downloads/82_IJFPS_March_2015_18_31.pdf ), and the explanation of "The Double Slit Experiment-Rexplained" at: http://www.iosrjournals.org/iosr-jap/papers/Vol8-issue4/Version-3/M0804038698.pdf ), is also correct, then I should explains the electron diffraction as carried in experiments by G. P. Thomson and C. J. Davisson and L. H. Germer on diffraction, which this paper is all about. In the experiment Young shined a light through two slits and observed interference patterns on a screen behind the slits. Fig.2-A, and resulted in the diffraction pattern shown in Fig. This realization facilitates the visualization of and it must be the same as without the detector B. (26) can be simplified, and given by, Solving the fixed parameters and radiation constant, But the inverse of 1.50918896109771160923234273, magnitude, the products of both the CMF (, constant represents the following two consta, Eq. However, the true nature of the actual possible nature of the space in which all the observable physical phenomena are being happening seems to be much much deeper than just being complex.. Determine the wavelength of light (1 Å = 10-10 m).. (b) The ratio of the intensities at minima to the maxima in the Young's double slit experiment is 9:25. In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena. In Section-III, it is shown that the inner-product of a state vector with its dual can be visualized as an interaction, us as a complex vector space as demanded by quan, associated with a state vector is shown to be responsible for which eigenv, quantum jumpâ are discussed in Sections VII and VIII, resp. (1) is termed as stated in the title and the Eq. propagators are derived using the Heisenbergâs equations of motion. of the spatial mode splitting into two components, the particle need not be a point particle. Also, it is shown that the classical and quantum mechanical times are one and the same. Observation over a large number of identical quanta, differing only by overall phases, results in the relative frequency of detection which yields Born's rule as a limiting case proving the absence of measurement problem in quantum mechanics. We present the results of a multislit diffraction experiment with such Therefore, according to wave-particle non-dualit, through both the slits simultaneously like a wa. (1) will be shown to be representing `Maya-advaithaM'; here, the word `advaitham' exactly stands for `non-duality' and there is no exact equivalent word in English to perfectly represent the term `maya'. both in the presence and absence of the grid. So, itâs clear that the space around us is indeed âcomplexâ in nature even though it is perceived âeï¬ectivelyâ, ES. The first experiment to demonstrate this was carried out by Davisson and Germer in the 1920’s. Both measurement problem and retrocausality are absent in the present non-dualistic interpretation of quantum mechanics. I then trace the complex experimental and theoretical route that Arthur Holly Compton followed between 1916 and 1922 that led to his discovery of the Compton effect, a discovery that Peter Debye also made virtually simultaneously and independendy. If the detector states do not have complete basis to span, Let us consider a classical scenario of tossing a coin in, possible, in principle, to predict exactly whether head or tail will o, force direction in a Stern-Gerlac (SG) apparatus, then the resulting situation of the coin is exactly identical to that, It can be easily seen that if the space is a complex-Euclidean instead of, or the complex-Euclidean space should be considered in such a way that it giv, coin, letâs consider an electron which is known to be zero-dimensional object and has a spin magnetic axis attached to. Phys. Hypothesis(2): location in the detector screen is due to the fact that the particle arrives there due to the momentum it carries. We hypothesize that the structure of the wave function for a quantum system at the sub-Planck scale has a deterministic cyclic structure. The schematic diagram of the experimental setup is shown below-Figure(1): Young double slit experimental set up along with the fringe pattern. old origin disappears and a new origin appears at the same instant, independent of the distance of separation between, In the case when the particle is subjected to some p, This non-dualistic picture of a particle ï¬ying in its own IRSM is not analogous to any classical w. If the particle is going to end up, say for example on a detector screen, then a dual vector. If slit-1 (slit-2) is blocked, then a clump pattern corresponding to a single slit diï¬raction of slit-2 (slit-1). Calculate the separation between adjacent bright fringes on a screen 5m from the slits is. 1. d is the distance between 2 slits, L is the distance between the slit and the viewing screen, P 2 is the distance between the second-order fringe and the center of the screen. −2, from leading experts in, Access Scientific knowledge from anywhere parameter ' is common to classical...
