I simply don‘t understand why the assumption that light moves as a Wave makes more sense than that it moves as a Particle... (I know that the assumtion is more about light „sometimes“ being a Wave, but that just makes even less sense).

Wouldn‘t it be more appropriate to assume that the probability of the particle being at a certain place is based on the Wave function?

Now what causes this probability of it deviating from the straight path can be anything from an unstable setup that slighlty changes the direction of the particle being shot, to any outside force change, but that‘s Not the point now.

If we shoot many particles (in a Computer Simulation) towards 2 slits and slightly modify the angle for each this will result in a pretty perfect interference pattern... and we have no particle being a Wave, or having anything to do with one.

Now if we have the amount of deviation as being inverse to the probability (smaller deviations happen more often), then the interference pattern looks pretty much like the ones seen in Double-Slits experiments, being brighter in the center than towards the sides.

So how come that physicists say it behaves like a Wave? Am i completely missing something about this?

Btw, i made a simulation with this assumtion and it looks just how it should...

Edit : This is close to what i got when i did the simulation. The simulation takes a lot of time, so i just made an image of what i got

This is what it resembles (not 100%, but that's due to the quality of the simulation) enter image description here

Turns out, that it resembles the 2nd image less, the further the particles travel...

  • So it will obey a wave equation but you will call it a particle? – Jon Custer Jan 06 '19 at 00:58
  • @JonCuster It is a particle and follows the path a particle should follow, but if you repeat it with slight deviations in its path (slightly changing the starting direction) the overall Image created is exactly what the Double slits experiment shows. – Lexyth Jan 06 '19 at 01:12
  • No, no it is not what the single/double/multiple slit (or edge) diffraction shows. Sorry, can’t do it with classical particles. – Jon Custer Jan 06 '19 at 01:20
  • @JonCuster Give me some hours and i‘ll include an image that shows what i got and that it ressembles the pattern. Now it might just be wrong, but i get the pattern and used particles... so... yeah, i‘ll just include an Image. – Lexyth Jan 06 '19 at 01:29

    In your simulation, if you cover a slit what do you get? – Francesco Bernardini Jan 06 '19 at 02:48
  • actually you can assume it is a particle if you like, see https://en.wikipedia.org/wiki/De_Broglie%E2%80%93Bohm_theory –  Jan 06 '19 at 02:57

    @FrancescoBernardini if i Cover one slit, then it creates 2 equal spikes with the center of both being directly under the Open slit... which shouldn‘t be... ok seems like i made some mistakes – Lexyth Jan 06 '19 at 03:23
  • I’m not sure I understood what do you get: as far as I know, when you cover one slit you should lose the interference pattern and get only one beam impressed right after the slit as if it was a straight trajectory; is that what you get? – Francesco Bernardini Jan 06 '19 at 03:47

    @FrancescoBernardini No, that‘s why i Said i made a mistake I get 2 beams with the „dark“ space between them being where the beam should be. Thus there has to be something wrong with my Simulation... – Lexyth Jan 06 '19 at 03:50
  • @FrancescoBernardini and Lexyth. Even with one slit or only an edge an intensity distribution behind appears. Even with single photons. On the over side this pattern hardly could be created only with different initial positions of the particles. In my opinion an interaction with the electrons on the edges surface creates the magnetic net sits distribution. Lexyth, it would be nice to publish not only the image but the equations too. – HolgerFiedler Jan 06 '19 at 05:21
  • @HolgerFiedler yes you’re right, i was forgetting diffraction; – Francesco Bernardini Jan 06 '19 at 05:31
  • @HolgerFiedler I‘m Not quite sure if i get what you mean, but if it‘s what i think, then that is pretty close to what i tried, but i just tweaked some values and it turns out that by changing the distance between the slits and the screen, this pattern that resembles the interference pattern splits up into different interference patterns that just go further and further apart. With the optimal State looking close to this . - . ^ . - ., but then expanding and becoming this . - . - . . . - . - . I know this isn‘t a good representation, but it should make the point and i can‘t insert Images. – Lexyth Jan 06 '19 at 05:33
  • @HolgerFiedler Basically what happened, is that the pattern split into mutliple normal reflections of each side and the particles that went through unimpeded. Seems like this is just a case of „It works, but only if you look at it with specific conditions“... – Lexyth Jan 06 '19 at 05:37

Just so there is a clear record: what you're seeing is not an interference pattern - it is just the shadow of the two slits. If you cover one of the slits, the expected wave behaviour is a pattern which is equally broad, but without any nodes. As you noted in the comments, that's not what you observe in your simulations.

  • It should be the real answer sought ....plus one – Alchimista Jan 06 '19 at 09:09
  • @Alchimista It is more of a record of this question and the answers and delivers an explanation to why i was wrong, but doesn't answer the direct question as precisely as the currently selected answer, at least in my opinion. – Lexyth Jan 06 '19 at 10:00
  • Yes that is possible. I have thought your simulation just challenged something that you were aware of. It was just an appreciation of the coincise answer. – Alchimista Jan 06 '19 at 10:18

Why can‘t the Double Slits Experiment be explained by a Particle?

In the standard model of particle physics the photon is a zero mass point elementary particle . These elementary particles obey quantum mechanical equations. When they interact it is the wave function that gives the probability for the path that the photon will follow . It is the probability that waves. In this double slit single photon experiment :

snglphot

Single-photon camera recording of photons from a double slit illuminated by very weak laser light. Left to right: single frame, superposition of 200, 1’000, and 500’000 frames.

the experiment is "photon interacting with two slits a fixed distance apart and a fixed width" for a given material whose atoms and molecules provide the potential with which the photon will interact.

The particle footprint is seen on the left the built up interference pattern , of the electromagnetic wave is seen on the right.

The standard model is a very successful model in describing existing data and predicting new set ups. Classical electromagnetic fields emerge in a complicated mathematically way from the quantum mechanical formulation with photons as can be seen here .
