      ​@@upandatom Don't we suspect those light "waves" propagate through something? Maybe the hard-to-find Aether exists everywhere.
      It might have its own set of rules, like an apparent wave/energy speed limit! It might also have something to do with applying the ubiquitous “pressure” called gravity and demonstrate the optical gravitational lensing observable on a cosmic scale or the magnetic optical deflection produced in a lab. Do we really know, for sure?
      Maybe those beam splitting phase detection and “photon - particle” electron counting experiments are somehow missing some other explanation for those observations/conclusions? Maybe Aether is also naughty, LOL.

Your 3D drawing along with the dashes and lines made all of the difference. Between your video and Vertasium's video, I think anyone can understand the double split. Thank you!

    Nice, simple explanation.
    My guess (and it is a guess) for the relative brightness of the bands -- the inverse square law. Since the bands to the sides of the center band are farther from at least one of the slits than the center band, they're dimmer.

    • @upandatom
      @upandatom  8 років тому +4

      Exactly! Pretty much the intensity diminishes with distance and the sum of the paths will be longer on the outer bright fringes. Great answer :) are you a physics major?

  • @Dyslexic-Artist-Theory-on-Time
    @Dyslexic-Artist-Theory-on-Time 9 місяців тому

    A logical explanation is that the electromagnetic field itself is not quantized and light as a wave can go through both slits at the same time. As waves, it can then form constructive and destructive interference. The energy transfer processes to and from the field is quantized with the absorption and emission of photon energy. In the reference frame of the experiment, this can be seen with the interference pattern forming out of a random statistical process photon by photon. In this theory this represents a universal process, we always have a probabilistic uncertain ∆×∆pᵪ≥h/4π future coming into existence with the exchange of photon energy. The wave particle duality of light and matter in the form of electrons is forming a blank canvas that we, as atoms, can interact with forming a future relative to our actions.

    I did the double slit experiment at home. I needed 1 laser, 1 very sharp knife, 1 piece of carton and a wall. Worked perfectly. Light (photon) is a quantum of electromagnetic energy in/on a probability wave. What I do not understand, is why light is not going around the piece of carton. According to Feynmann, the light wave takes all the possible paths in the universe, only with different probabilities.

    • @symbioticcoherence8435

    The question’s answer is that in the side waves, the last yellow line does not have a interference with another yellow line while in the middle one, that happens. So the middle light line is little brighter than the sides

  • @ishanr8697
    @ishanr8697 3 роки тому

    Good explanation, but the light doesn't necessarily have to be monochromatic. Young actually did his experiment using sunlight!
    The light does need to be coherent, so he used a single slit to ensure coherence, then a double slit to see the interference pattern. So sun -> pinhole (or single slit) -> double slit. Try it, you will see a really interesting pattern appear!

    This theory explains the Two Slit Experiment with the future as an emergent property within the
    reference frame of the experiment! In this theory the mathematics of quantum mechanics represents the physics of 'time' with the future coming into existence photon by photon within an infinite number of dynamic reference frames. The wave particle duality of light creates an interactive process acting like the bits or zeros and ones of a computer. This forms a blank canvas that we can interact with turning the possible into the actual as the future unfolds photon by photon.

    A wave is spread across. In a double slit experiment, if the wavefunction representing the electron, hits the slits, shouldn’t that be a measurement and shouldn’t that collapse the wavefunction? Now, you'll say it's not a physical wave, it's a probability wave. But then how does a probability wave split into two after the slits? Then, it should be like, the wave hits the slits, the electron says, dude I'm going through the slits, so don't collapse, but you can split into two and diffract. When does it decide that it's going through the slit?

    • @schmetterling4477

    It's good to see that parents are watching and learning along with their kids. Mine are all grown up, so now it's my turn to learn about some of the many things I put on hold to raise them. Your videos are easy to understand, and then relate to real life experience. I've probably seen this experiment talked about a dozen times, probably more, But I never got it until now. Thanks!
    So now, a (maybe) dumb question. Would the reason that the answer can be found within the inverse square law be, because the angle of refraction is larger in the outer light fringes, which results in fewer available photons? Maybe from more scattering? (IDK) But, if so, then less density = less brightness?

    • @upandatom
      @upandatom  8 років тому +1

      +Karl Kiefer it's good to hear that you're taking the time to learn about this stuff. It's never too late!
      And no question is dumb. Physics is hard. All of it. If I understand correctly what you've said you're exactly right. The larger angle means the sum of both distances from the slits is larger. So the photons have further travel at the outer edges, so by the time the light hits the detection plane it has diminished in intensity. You can try to visualise it with water waves. The further a wave travels, the smaller in amplitude it becomes. The exact same thing is happening here.
      Stay curious!

  • @christopherevansanders3629

    Light and its nature have caused a lot of ink to flow during these last decades. Its dual behavior is partly explained by (1)Double-slit experiment of Thomas Young - who represents the photon’s motion as a wave - and also by (2)the Photoelectric effect in which the photon is considered as a particle.
    A Revolution:
    SALEH THEORY solves this ambiguity and this difficulty presenting a three-dimensional trajectory for the photon's motion and a new formula to calculate its energy.

    • @schmetterling4477
      @schmetterling4477 3 роки тому

      There are no particles in nature. That just an old myth similar to the phlogiston and the aether that just doesn't want to die. The only thing you are measuring in quantum experiments are irreversible energy exchanges between quantum fields and external physical systems (aka "the detector) that we call quanta. Quanta, however, are not particles, they are a new and fundamentally different concept. So whenever you hear somebody talk about particles in quantum mechanics, you know that they have it all wrong. In any case, Young's double slit experiment from 1801 was conceived as a wave experiment and it can never be anything else than a wave experiment. How can you see this? Planck's constant, which is the hallmark of something quantum mechanical happening, is nowhere to be seen. If the double slit had been a quantum experiment, Planck's discovery would have been made by somebody else (maybe even Young) a full century earlier.

      He wouldn't have known that because you can make these slits as large as you like and still get interference effects. They will simply happen on a smaller angular scale, which means that one has to move the screen farther away to observe them. That feature sizes have to be the size of the wavelengths is a typical misunderstanding of wave optics.

    You should get the Stephen Hawkins science award for the promotion of science. He gave it to Dr. Brian May(guitarist of Queen). And your so beautiful Jade. I’m always watching your UA-cam lessons in physics. Love you Jade. You should be in Hollywood. Your a star.

      +Symbiotic Coherence haha I never even considered the LGBTQ+ thing! Now it seems obvious lol. Well I'm glad I didn't disappoint :) welcome to the channel!

      thank you! btw: you don't need a split the size of the wavelength. At school we had 80 slits per millimeter or 2 slits with visible width; and those worked fine.

      Yeah they need to be comparable to the size of wavelength, which is a pretty vague statement... But thank you for telling me about your experiment I did not know that :)

    Everyone has seen a wavefront at a beach. Easier to explain that way. Everything is easier to understand at the beach.
