@@SimonPoliakoff is this an assumption or have you tested it with both vertical and horizontal blades(both together)? I have a fun anti-thesis. If indeed there is circular banding, then yes it is wave-particle duality BUT if it is simply horizontal (or vertical), then this is because the particle is oscillating perpendicular to the motion and bouncing off the edge of the slit (classical non quantum model).
Not sure but when you have the double slit experiment light diffracts through both slits spreading out. Then where the light from both slits overlap you get interference creating the equally spaced bright and dark fringes.
@@SimonPoliakoff thank you for your reply! My initial understanding (based on the standard textbook explanations) was that there is no wave-like behavior in a single slit experiment, however given that a single slit shows both dark and light areas, it seems that there is a wave-like behavior even in a single slit, therefore the significance of the double slit experiment (vs a simpler single slit) is lost on me. In a single slit experiment there is no interference between the photons going through the different slits, but you still need to explain the dark areas. I understand, the photons (even different wavelengths) do not cancel each other out, so the appearance of dark areas is puzzling.
Imagine that each tiny part of the slit is a source of waves so across the width of the slit there are hundreds of little sources of waves. At some angles all these waves interfere constructively which creates a bright fringe and at other angles they interfere destructively which creates a dark fringe.
@@SimonPoliakoffThen why don't we see interference in case of water waves passing through a single slit? That seems inconsistent for how a wave should behave.
How come there is a interference with single slit? I've watched video about quantum mechanics, and it was said, that proof of quantum effect is interference in double slit experiment. So if interference is visible even with single slit, than what kind of proof is that? I do not get it.
You can understand the single slit pattern as waves from across the different parts of the slit interfering with each other. I might make a video explaining it when I have time.
@@SimonPoliakoff Thank you. So what is so special about double slit if the same can occur with single slit? I bought single and double slits from aliexpress and when I passed laser light through one slit I was confused.
The edge of this slit is made of atoms after all, light is an electromagnetic wave, so light superpose with electromagnetic wave of electron, and give such pattern.
Puzzled by why the waves are always horizontal. No one ever seems to wonder or explain why this happens instead of a spherical pattern
it is because it is a vertical slit. If it was a small circular hole then you would get circles.
You can also get a circular pattern by simply tilting the aperture vertically, like a drawing table.
Why the camera is round, and the photos are square?

@ It works with any orientation of slit
I will use this video in a video, the deadline is in 20 hrs so I can't wait for your response, sorry!
No problem if you acknowledge and it isn’t commercial.
Thanks, helped me with it. No more confusions
So why almost all textbooks and videos explain the significance of the double slit experiment by showing that a single slit does not diffract?

@@SimonPoliakoff I was wondering why there were dark spots. Thanks

It looks like you created a magnifying glass?
No just an adjustable width single slit and an iphone se 2016 taking a close up view of the diffraction pattern.
Can we use this single slit experiment to explain Heisenberg's uncertainty principle?
This discusses it: www.quarknet.org/sites/default/files/Heisenberg%20and%20Diffraction.pdf
Try bending the laser around a glass instead of straight on
What are you trying to show with this?
is this fraunhofer diffraction? that's what i'm saying in my thesis
Yes.
