I see what you did there

Why would he not discuss the most important part? The knowledge of the data and how it changes the results.

The pinhole-pair itself is not covered, but it is really small in the center of the disk. The tape (and tinfoil below it) is to keep stray light out of the tube. To see the image you have to look through the tube, through the pinholes, at a light source. My best results were from streetlights and stoplights at night. To avoid damage to your eyes you do NOT want to use this type of system to observe laser light or light from the sun.

Have you used coherent light sources in this experiment? I am not able to understand why the intensities of the maxima keep decreasing... could someone please help!

I'm sad I didn't get to see a single photon emitter with results from it being observed vs not being observed. Thank you for the demonstration.

Nice video Bill. Why is there a wave pattern on the back wall when the beam is going through 2 slits when we, or you, are observing the beam? Doesn’t the wave pattern cease, and instead shows up directly only behind the 2 slits, when an observer observes the particle in the original DSE? Isn’t that the main reason for the popularity of this experiment “the act of observation changes things”?

IMO, a "quantum vibrational wave/ripple" is set off at the point where the electron is fired. A quantum aerodynamics of sorts. The wave precedes the electron. It is this wave that is responsible for the distribution pattern as each electron, even though fired 1 at a time, is carried on it. It explains the "probability" of where each would land. When you try to measure the electron, it is not the "conscious" act of doing it that causes the electrons to behave as particles, but it's because you break the wave. Thus, as there is no wave for the electron to ride on, it will come through the slit as an independent particle.

What happens to the particles that hit the barrier? They whould be bouncing and making another patter somewere else. A patter that is not being observed. And if the pattern is not being observed , will it be afected when the experiment IS OBSERVED?

nice job. I'm wondering if no one's tried to slow the thing being tested down. Perhaps making it pass through a medium or a very very cold vacuum? Also, Sean Carroll speaks of everything being a field and I'm imagining a wave or disruption in a field. It's certainly an odd thing this dual nature of stuff. The peaks in the waves being seen as particles or probabilities for particles etc. Light passing through a vacuum without a medium to carry the wave is another strange one that brought us back to particles and corpuscles didn't it? I'm still not seeing how it can be both forms, it's especially strange when you're talking about one atom or photo at a time. I hope this is resolved in my lifetime. Excellent thought provoking video presentation.

Linear superposition means that light never gets in its own way. The physical conditions for gamma-gamma scattering and vacuum polarization are nowhere near met for visible light at the kinds of intensities that we are talking about here.

For the best explanation I'd probably go to the Feynman videos, but the thrust of the result is that photons are particles and can be observed as such. The wavelength and wave properties all relate to the probability of finding any one photon in some region, and the interference pattern we calculate classically describes how we expect the photons to be distributed on the screen. cont...

This video seems to lack the fact that if you attempt to observe each slit to see which slit a photon is travelling through you no longer get an interference pattern. Instead light reverts back to acting like a particle instead of a wave.

Is it even possible to measure light in an experiment with a device that uses electricity as its propulsion. In that I mean to say, how are you using something that is not as fast as light AKA electricity , to account for particles that move faster than the electricity and therefore cannot account for every possible particle.

A quantum is simply an amount of energy. If your detector can resolve the amount of energy in the quantum, then it will be a single quantum detector. Some detectors take longer to achieve that resolution and some can do it quickly, but the time resolution of the detector is a completely independent question of the speed at which electromagnetic energy propagates. The most simple detector for single quanta is called a photomultiplier tube. A small one costs a couple hundred dollars new and you might be able to pick a used one up in working condition for a fraction of that.

I watched this video several times, but I couldn't figure out how the pipe is supposed to work. Because the other end is taped completely. There is no opening for the eye.

+John Batibasaga Yes, I did, but it was quite a steep learning curve. Here's the upshot: if you fire single electrons at two tiny slits in a screen, what you will get is an interference pattern - very paradoxical, since you have particles acting like waves. But if you use a detector on the other side of the screen to determine which slit the electron has passed through, you will get two bands. The electrons are now behaving like particles. Why? Because by detecting, or taking measurements of the electrons, you are actually taking information from them, and they go from probabilities (waves) to discrete trajectories (particles). This is called a Wave Function Collapse. It's important to distinguish between "observing" and "measuring." Merely observing the double-slit experiment with your naked eye isn't going to make the interference pattern collapse. This is a very widespread and misleading misconception. You have to take actual measurements of the particles (photons or electrons, or atoms) after they have passed through one slit or the other to cause them to collapse into two discrete bands .

Could it be possible that by measuring at one slit, energy is being absorbed, effectively creating two different light sources that aren't in phase and don't interact.

So has anyone found the answer?? Does anyone think consciousness has anything to do with it?? If that’s the case that would open up a huge ballgame? And tell us a lot about ourselves. IMO, help I need answers/ opinions???

Stand back further you don't see the particle nature of images :)

I do understand that the scientific community has pretty much accepted particle/wave duality, but I believe there is a simpler answer that makes more sense. The double slit experiment makes perfect sense if light is a waveform because of the interference patterns. The reason people believe its a particle and wave could be partially due to the assumption that what they are emitting is light. If an electron is emitted, it will create an electromagnetic field around it much like a wake from a boat or when it impacts other matter. The electron itself is not light. This theory is very testable. perform the double slit experiment in a total vacuum, there should be no interference pattern. Another reason why people believe light as it's particle form is because of the way it behaves in space. For example, how could light travel through space if its a vacuum, or why does a black hole or massive objects cause light to change direction. This could be answered the same with sound waves. Does sound travel in space? No. Does Light travel in space? Actually no. Electrons striking the atmosphere impact create the electromagnetic wave which we see as light. If you were to put a camera in space, the electrons would contact the CCD on the camera and create the electromagnetic wave directly on the camera. But technically by this theory the light doesn't exist in space until it contacts matter. This makes perfect concerning black holes. black holes have a lot of mass, electrons have mass. The same could be said about sound in space, an object traveling in space hits your space helmet, you would hear it as the object would create the wave when it contacts you. So the sound doesn't travel in space, but you will hear it when it hits you. black holes effect the trajectory of electrons, problem solved. According to common scientific belief, "photons" have no mass. How does gravity effect the path of light then? My theory has huge consequences on the way everyone views the universe. Speed of light is not constant, just like sound. Sound travels slower or faster depending on the propagation medium just like light. In fiber optics, this concept is known as refractive index, because light waves travel 1/3 slower through fiber optics. This would mean that there may be some errors in the way which people theorize the distance of the stars using the speed of light, although the actual light waves do not travel through space.

light is an electromagnetic wave, it only propagates through mass. electrons can travel through free space though because they have mass. Elections or subatomic particles striking other mass create the electromagnetic wave which we know as light. Think of sound for example. Sound is not a particle-wave like a "phot-on", there is no such thing as a "sound-on" nor a photon. Sound cannot travel through space, neither can light. If we were in space and I threw a rock at your space helmet you WOULD hear it though, because the rock impacting your helmet would create sound waves internal to your space helmet. It's the same thing with light, light doesn't travel through space but an electron impacting your eye or camera lense would create a light wave on impact.

jakeflow27 I'm confused, what do you mean there's no such thing as a photon? Are you saying light can only travel through space via the medium of an electron? I thought light travelled through space in the form of a photon? When you shine a torch, you're not firing electrons out of it, the electrons in the element were excited and then the equivalent energy released as the electrons return to its natural state is what we see as light. So if light is energy, are photons just energy? How could it then exhibit some aspects of a particle wave as energy cant have matter... I think I need to research what exactly photons are

zedooncadhz in school people are taught about photons. im telling you my opinion that to me it makes more sense that light is ONLY an electromagnetic wave, like microwaves or radiowaves. nobody believes in micro-tons or radio-tons but they are known to travel through space. waves need a medium to propagate, that medium is matter, light propegates differently in different mediums just like sound. light travels slower in water and fiber optic lines. sound travels slower in water as well. the fastest speed of light is in a vacuum which is the speed of what the particles (electron or other charged particle) travels. light is effected by gravity in space, thats a known fact, but im saying thats not light, its the particles which are going to create the EM wave on impact

I believe QM is wrong in their assumptions. There are no mythical photons as particles or photons as waves. There is only a probability field. Move the back wall so that it is directly behind and touching the double slits. Do the experiment (I imagine you'll get two bands). Then move the back wall far enough away to get multiple bands. Then move the back wall in 12 incremental steps towards the double slits and pay attention to the pattern created as the wall is moved to new locations and changes. My contention is that just like in music you are proving there is a frequency that is being affected, the frequency of the probability field, proving QM to be utter nonsense. Imagine a guitar playing an open note. This is the state without an observer. Moving the back wall towards the slits would be like fretting a note and moving your thumb towards the bridge of the guitar, wherein you increase the FREQUENCY of the note. Adding an observer could be like muting the frequency. Physicists get confused because they SEE things in visual terms or in mathematics. But what if a physicist is a musician and HEARS a conclusion to a puzzle using music theory, that otherwise wouldn't be considered?

The point of Thomas Young's experiment was to determine if light is a wave or a particle. That's it. In 1805 the whole topic of Quantum Theory was still almost 100 years in the future. The question at the timie Thomas Young lived was: particle or wave, which one? Newton had good reasons to think it was a wave. Young's experiment (in the context of knowledge of his time) showed without a doubt, that Newton was wrong. Light was a wave. And it was treated as such nearly 1 hundred years, until some doubts showed up in the form of additional experimental results and the idea was born, that there must be more to it. That is why the experiment is called "Young's double slit". Its only purpose is to show that light behaves as a wave. Nothing more, nothing less.

We all know that Pythagoras, Plato and socrates studied in India. Hindu Vedic book Rig veda (5000 BC) clearly says that Energy and matter are Inter-convertible. It also talks about electromagnetic field According to Advaita philosophy of Hinduism by Adi-Shankaracharya (2000 BC) "All that you see does not exist"..which is validated by the so called double slit experiment. West thought that earth was the center of the universe (Geocentric) until 300 to 400 yrs ago but brilliant hindu mathematician and astronomer Aryabhatta (2750 BC) was the first to say from vedas that Sun is the center of the universe (Heliocentric). Smart people of the west sent Galileo to exile for repeating Vedas by saying that Earth rotated around the sun. LOL Earth goes around the sun - Rg Veda 10. 22. 14. and Yajur Veda 3. 6. Sun and whole universe are round - Yajur Veda 20. 23 Shape of Earth is like an Oblate Spheroid. (Rig VedaXXX. IV.V) Moon is enlightened by the sun - Yajur Veda 18, 20. ‘Earth is flattened at the poles’ (Markandeya Purana 54.12) Blue Sky is Nothing but scattered sunlight (Markandeya Purana 78.8) There are many suns - Rg Veda 9. 114. 3.

The gravitational effect of solar system makes the earth stable (R.V.1-103-2, 1-115-4 and 5-81-2). The axle of the earth does not get rusted and the earth continues to revolve on its axle (R.V. 1-164-29) The Sun never sets or rises and it is the earth, which rotates (Sama-Ved 121).

This is such bullshit. The reason individual photons of light exhibit the interference pattern is because of time dilation. Photons are already traveling the speed of light, so for them time has completely stopped. Thus it doesn't matter how long the interval between each photon; as far as the photons can tell they have all been fired together.
