    Light reacts with the field of the matter holding the slits and surfaces, so various types including carbon to be electrically neutral have to be used.

      @@QuantumLab-bt7yq If you find your matter holding the slit has a charge, then make it grounded neutral or charge is up + or - is the obvious next steps. In fact, you don't need matter at all for a slit, it would seem vertical laser beams could be used for blocking but the outcome could be unusual. If opposing photons produces a pattern different than matter, then we learn something more about light behavior.

    I have been "playing" with lasers since the mid 1980's when I built my first HeNe laser in my living room.
    This brings up the question regarding color. This experiment uses a green, shorter wavelength and the results are obvious. So how would a longer wavelength red work out? Will the battern be wider spaced?
    I do have a blue laser, but it has a focal point for burning and at 6 Watts output, might be a bit dangerous for this type of experiment.
    The red laser is still functional, and I will see what kind of results I get. The beam is much narrower so it may take a little creativity to duplicate here.

      found the following using google
      Shape
      When light with a longer wavelength is used, the interference fringes will be wider and farther apart.
      Spacing
      For example, if red light is replaced with blue light, the fringe width will decrease, meaning the fringes will be closer together.

    2:47 I noticed the thick part of the caliper jaw is being used instead of the sharp/tapered part. I found this an odd choice as it puts more material in the path of the photons between the source and the destination.

      My premise is the photons bounce of the edge. My guess is the second pattern is a reflection pattern. Something you will never see in a ripple tank demo.

    The problem is quantum labs does not understand the expeiment proving that light changes it's behavior if it's being directly observed. IE: Actual scientific experiment results are different patterns develop, depending on the simple act of turning on a detector to see the photons travelling. Fact: Photons behave differently if they are being directly observed, and that is what no one can explain.

      The observation is not visual. It's with an instrument. That is what confuses a lot of people! If you put an instrument in light's path, it's perfectly understandable that light will be affected. Nothing conscious on light's part. Be rational.

    Water or air against a surface is not particles and a surface. The behavior is particles against particles against a surface. This causes their velocity to slow down in contact with a surface due to friction, producing curvatures in wave patterns. The slower reflections against the faster outer water produces interferences. You are showing that photons do not slow down closer to surfaces. The surfaces can reflect water, but the light is absorbed by your surfaces since you did not use mirror surfaces. Next, aluminum foil surfaces.

    • @SciD1
      @SciD1 Місяць тому

      No, light does not lose velocity due to friction when reflecting off a surface. The speed of light remains constant when it reflects, regardless of the surface it encounters. However, the intensity (or energy) of the light may decrease if some of it is absorbed by the material, but this does not affect its velocity.

    There simply is no "quantum weirdness". It's a 200 year old misinterpretation. Light was never a "wave". Quantum mechanics is nothing more than a probabilistic mathematical framework based on the misunderstanding and the misinterpretation of the nature of light, and the double-slit experiment. Maybe that's why it is "probabilistic"... The math may be useful for replicating technology and chemical reactions, but it has no bearing on reality itself, because the theory is founded on the fallacy of quantum state superposition.

    There is also single slit interference. Because there is also single slit interference when the width of the slit is comparable to the wavelength. So if you analyze the geometry of the waves carefully, and apply huygen's principle, you will find that a single slit should also have places after the slit where the wave front has traveled different distances, and so there should be interference from only one slit. But you only see it if size of the slit is comparable to the wavelength.
    Also, you don't understand the conclusion of Young's experiment. Your version also confirms that wave mechanics govern light.

      @@QuantumLab-bt7yq I like the fact that you are not content with the textbook description- you want to see it yourself. But I think you'll go farther if you augment your knowledge with the textbook description. Don't shy away from the math- it can all be done with rules of triangles, if you like geometry better.
      I've never tried it with water, but my guess would be that you need the aperture to be the size of the wavelength, and you need to look for the interference much farther to the sides. Remember the single slit interference pattern has a very strong peak that is wide compared to the double slit pattern. So you're looking for the place where the waves are very small amplitude, and fairly great distance from the center. The laser has a wavelength that is microscopic, and so you are only looking a fraction of an inch to the left or right to see the fringes. But the wavelength of your water waves might be a million times greater. So you're looking for interference in the very small ripples, far to the sides. And it will be quite a bit less noticeable than the double slit.

      @@vwcanter You present a valid question. One i wrestled with for a long time. I am familiar with Huygen's theory. Have yet to see any experimental evidence to support it. The biggest flaw in quantum wave theory is the assumption photons interact with each other. They do not. Suggest searching DO PHOTONS INTERACT WITH EACH OTHER. They pass through each other unchanged. You can do the experiment yourself. Any two lasers will do. Several years ago I bought a laser and started doing experiments. That is when I saw photons do not act like ripple tank demos predict. That realization led to my guardrail experiment. I placed a barrier between the two slits preventing interference. With the barrier in place we still see a light dark pattern. The experimental results indicate if quantum wave theory is going to survive it needs a better explanation.

      It's so funny how you people use waves the way it suits your needs. Sometimes physical waves, sometimes probability waves, or waves of math. The double-slit experiment has been interpreted as light interfering with itself for 200 years! You will literally find thousands of videos on UA-cam claiming light behaves like water waves. The fact remains, nobody has ever observed light waves, and never will. It was Young's interpretation, pure assumption, and it's nothing more than that today.

      @myspeechles How do you explain the "interference" pattern when you fire many photons through a double-slit, one at a time? You can either invoke MWI, or interpret the photons as "waves".
