The double slit expiriment demonstrates the duality of the nature of a photon: that it’s both a wave and a particle.
When a photon is “observed” (or detected) it has the properties of a particle. However when it’s travelling it acts like a wave and can demonstrate interference patterns with other photons.
So when you pass photos through two tiny slits, instead of them just passing right through like a particle, they interfere with each other and when the wave pattern collapses when it is observed on the wall, you see the interference.
That being said, I don’t think this cartoon makes sense. I get what they are driving at, as they are saying it acts differently when not observed, but this is not what happens. Also this isn’t a ln experiment that deals with observation forcing an outcome, but as I noted it’s about the duality. Additionally, the wave pattern on the top is what you would you observe when looking at, so I’m not sure why that is what it would be like if you were looking away.
When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.
Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.
When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.
The interference pattern only appears after firing many many photons. They’re still a photon (packet of energy) when creating an interference pattern. It’s the distribution and probability of its location that changes. Not the physical “shape”.
Edit: to clarify further
When not being detected, it’s still just one dot that appears on the sheet. As more and more are fired, the interference pattern shows to show as each photon hits the screen
Can someone who understands science explain this to me (what im getting at is its a pregnancy test)

But maybe I’m missing something.
The double slit experiment is about observation.
When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.
Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.
You’re right, I forgot about this part of it.
The interference pattern only appears after firing many many photons. They’re still a photon (packet of energy) when creating an interference pattern. It’s the distribution and probability of its location that changes. Not the physical “shape”.

It’s all about the distribution possibilities.
Thanks mate.
