    I love how you manage to perfectly demonstrate fundamental physics concepts in a way that most school demos have trouble with. The fact that it's all a simulation means you can remove unnecessary variables like friction, and tweak things like wave speed. It's awesome.

    Beautiful video. At 11:40, shouldn’t it be reflected amplitude - initial amplitude = transmitted amplitude?
    Also if I stack up 3 materials one after another with v1=1, v2= 10 and v3=100, would I be able to cascade the equations to get a final amplitude of (2 * 10 / (10 + 1)) * (2 * 100/ (100+ 10) = 4 * 10/11 * 100/110 = 4 * 100/121 = 3.27 or do the waves and its reflections interfere, hence changing altering equation and we get a much lower value (lower than 2).
    I believe the equation above comes from the tension equation (balanced forces at each point in the material) along with conservation of energy!

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  4 месяца назад +2

      The equation in the video is correct. One way to see this is by thinking about the example where the reflected amplitude is zero (V1=V2). In this case, the initial amplitude should equal the transmitted amplitude, as is shown in the equation in my video. By contrast, in the equation you wrote, you have transmitted amplitude = -initial amplitude. As for your second question, if you stack up materials as you describe, you can get an amplitude in the final material more than double that of the initial wave.

    I work in electric power distribution and we have to sometimes place extra lightning arresters at the end of power lines due to the wave doubling effect at the velocity = 0 boundary. When lightning strikes a power line it creates a traveling wave along the line that reflects at the end and creates huge voltages.

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  4 месяца назад

      Actually, it is the open boundary where the voltage is double. By the way, the equations are different for electric transmission lines. I have a video on transmission lines at ruclips.net/video/ozeYaikI11g/видео.html

    Some sources claim that the group velocity of a light wave can exceed the speed of light. Although I understand that this doesn’t violate causality or the transmission of information, it would be helpful if you could make a full video explaining this, as many people use it to argue against Einstein's theory of relativity.

  • @drdca8263
    @drdca8263 4 месяца назад

    Does this apply to photons even though they move at relativistic speeds? I would have expected that, if we have the wavefunction of an individual photon as the wave, that the part reflected vs transmitted would be like, the superposition of whether or not it was reflected,
    But, in that case, I would expect the squares of the amplitudes to add to the square of the original amplitude (the squares of the amplitudes of the reflected and transmitted parts being the probability of it being observed to have been reflected or transmitted respectively), rather than the amplitudes adding to the original amplitude?
    Maybe this only applies in the situation with a large number of photons? Like, if the amplitude isn’t the probability amplitude, but the photon number or something?
    Am I making a silly mistake?
    Uh, if we have a Bosonic Fock space and for the single particle, in state psi_1 , uh, U(psi_1) = sqrt(p) psi_2 + sqrt(1-p) psi_3 (with psi_2 and psi_3 being orthogonal states)
    Then, the analogous thing to U with domain the Fock space, would send the vector with N copies of psi_1 to…
    uhh…
    Well, the N copies of psi_1 can be obtained by the N-th power of the creation operator for psi_1 , applied to the vacuum vector..
    and then, F(U) (a_1^*)^N Omega = (F(U) a_1^* F(U)^*)^N F(U) Omega
    which is probably = (F(U) a_1^* F(U)^*)^N Omega ?
    which is maybe (sqrt(p) a_2^* + sqrt(1-p) a_3^*)^N Omega ?
    Which seems like it would be…
    well, the a_2^* and a_3^* should commute with each-other due to it being the Bosonic Fock space,
    so, should be like, sum_{k=0}^N binom(N,k) sqrt(p^k (1-p)^{N-k} ) (a_2^*)^k (a_3^*)^{N-k} Omega
    Which, wait, that isn’t properly normalized because the binomial coefficient would get squared… uhh… I made a mistake…
    If N is large… I guess the variance in “how many are reflected” only grows as sqrt(N) , and so the variance in the fraction that are reflected goes as sqrt(1/N) , and so goes to zero as N goes to infinity.
    Hm. I don’t know relativistic QFT. I guess for non-relativistic quantum mechanics, I can’t really have the wave speed be independent of the frequency… can I? Not for a free particle in any case…
    (Though, presumably something similar should be true for phonons, and those don’t have relativistic speeds, so, it should be possible to relate what is described here to a limit of a large number of phonons?)
    Ok, yeah, while I imagine that what is described in the video probably applies to light, I don’t know how to relate it to a quantum mechanical picture.

    Было бы круто увидеть серию визуализаций взаимодействия электрона атома с порцией эл-маг волны на основе модели дипольного излучения/переизлучения, когда первичная порция проходит, раскачивая электрон, но следующая за ней порция с запаздыванием начинает складываться с переизлученной электроном порцией. в нескольких вариантах сочетаний частот проходящих и переизлученных волн. И следом уже взаимодействие плоского тонкого слоя атомов с плоской проходящей волной, как складываются волны от нескольких электронов в плоскости, порождая замедление групповой скорости (иллюзия замедления эл-маг волны в среде). Ну и добить визуализацией с толстым слоем.
    Это даст относительно наглядное представление, чем "свет", как образ нашего мозга в ответ на обработку распределения проинтерферированной напряжённости поля, отличается от реальной эл-маг волны, как он отражается от плоской "зеркальной" поверхности и от неровной поверхности, почему для света существуют кажущиеся нам законы отражения и преломления (замедления света) в веществе

    When unabsorbed heat singularities strike resistance lights up the mass, it strikes like a filament vibration. Lightning is rapid heat loss striking atmospheric gasses lighting up surrounding atmospheres from instantaneously disolving internal magnetic fields grounding currents through its nucleus or core where external heat energy force is strongest as external heat energy outside of entanglement of mass as potential renewable heat energy when absorbed into internal magnetic fields. Unabsorbed instantaneously disolving internal magnetic fields as external heat energy force of pressure as fire lines in the sky like forest fires. Waves crash the beach or rocks with overspray. Electricity is rapid heat exchanging through mass as grounding currents into earth's internal magnetic field. When heat can't rise above the cold atmospheric gasses, it condensates. Heat tunnels through the eye of the storm until pressure is equalization to magnetism centrifugal force cycling circulation within and without entanglement of magnetic fields as external heat energy singularities within and without entanglement of internal magnetic fields grounding currents through its nucleus or core where force is strongest around it. Hurricanes and tornadoes spinning all external heat energy faster than normal momentum of space itself. Centrifugal force within and without mass equalization of pressure. Heat cycling circulation patterns around cold repulsion of space as the nucleus neutralized repulsion within mass as outward force of pressure. Hurricanes and tornadoes are outward force of pressure in repulsion to cold space itself within and without entanglement of internal and external magnetic fields like black holes. External magnetic fields spinning around these monopoles of pure cold repulsion within the nucleus or core where external heat force is stronger at the event horizon perimeter. Tornadoes and hurricanes work as magnetic fields. Magnetism explains everything about physics.

      You are right Sir, people who don't like to watch educational videos with intense background noise are not eligible to watch videos on this channel.

    For waves on transmission lines, this treatment is not correct. Wave velocity mismatches don’t matter - impedance mismatches do. Two cables with different velocity factors but same impedance will have no reflection at their union.

      I knew that someone bring this up, which is why I stated in the video that these equations are different for transmission lines. This is written at the bottom of the screen at 10 minutes and 10 seconds into the video. I have a separate video for transmission lines at ruclips.net/video/ozeYaikI11g/видео.html
