How can a photon, or any other particle, interfere with itself? What does the uncertainty principle have to do with it? Why can't a device be used to track particles/waves? Please help with real answers! Thanks!
Strafespar said:I ment, when we measure a electron it collapses the wave function. How does that work?
phyfreak said:^^ every thread has the same answer, as far as what I can gather,
collapse = 100% probabilty of finding the particle. If we do that then the inference is gone isn't it ?
So, basically measurement causes the dissapearence of the inference, the seems implausibl :(
now still even if we don't measure, then the inference means the particle is passing both the slits at the same time IS IT SO OR NOT ? please answer this specific point as this creates doubt.
phyfreak said:^ photon.
phyfreak said:Ok so there have been experiments where only ONE photon was fired and it produced an inference OR we can't define what is " ONE photon " so there is no possibility of conducting an experiment with a single photon ?
phyfreak said:^ Thank you for the link, I clarified some misconceptions and is forcing me to believe in non locality but still I hold the the LHV theory supported by Eientien
The paper clearly stated that a photon if fired singly and then won't be able to produce the inference but over some time it will i.e the photon is passing one slit but we can't know which one. This is rather strange, I hope a quantum level extra dimention maybe able to solve th rpoblem rather than complex and implausibl theory like the MWI or copehangen.
Single photon is single "click" in photon detector.phyfreak said:Ok so there have been experiments where only ONE photon was fired and it produced an inference OR we can't define what is " ONE photon " so there is no possibility of conducting an experiment with a single photon ?
If you consider light to be quantized then single photon can't be split.phyfreak said:afaik photons r packets of lights isn't it ? I believed that the same single packet of light may somehow maybe split a good way to check this would have been to check the brightness of the inference wrt to the orignal source :)
The double slit experiment is a classic experiment in quantum mechanics that investigates the wave-particle duality of light. It involves shining a beam of light through two parallel slits and observing the resulting interference pattern on a screen behind the slits.
In the double slit experiment, photons (or particles of light) are sent through the two slits and then they interfere with each other, creating an interference pattern on the screen. This is possible because photons exhibit both wave-like and particle-like behavior, allowing them to interfere with themselves.
The double slit experiment provides evidence for the wave-particle duality of light, which is a fundamental concept in quantum mechanics. It also demonstrates the strangeness of the quantum world, where particles can behave like waves and interfere with themselves.
Yes, the double slit experiment has been successfully performed with other particles, such as electrons, protons, and even large molecules. This further supports the wave-particle duality of matter and shows that the phenomenon of interference is not limited to light.
The double slit experiment has led to the development of technologies such as holography and diffraction gratings. It also has implications for quantum computing and cryptography. Additionally, it has helped scientists better understand the nature of light and matter, leading to advancements in the field of quantum mechanics.
