Here we can see a problem. It's as if the writer never really perform the experiment himself. A double band pattern on the screen is only possible if the width of the slits are large enough so diffraction effect is insignificant. But it means that there would be no observable interference effect even if no detector was placed right before the double slit.

But here is where it gets interesting. If you place the detector after the slit there will be no interference pattern. Even after the photon left the slits as a wave it somehow freaks out and tells itself to act as if it came out as a particle. This is a delayed-choice double slit experiment.How could a photon change what state it was, in the past?Well trying to conclude that the photon was either a wave or a particle in the past would have to imply some form of time travel. Instead, physicists tend to conclude that it is neither a wave nor a particle. Rather a photon remains undefined until the measurement which prevents the need to bring in time travel.

I haven't found something like this being demonstrated in an experiment.
Yes you have; you just didn't realise it.

Once again, we see the dangers of confusing a model with an object, and using animalistic terms like "behave" as if our object had reason and choice.We have observed the properties of electromagnetic radiation. We do not have a unique mathematical model that describes and predicts all of them, but by using two models we can get very close. Why make it any more complicated?
The super bizarre quantum eraser experiment
Here's my newest video investigating diffraction of light by producing single side interference pattern.//www.youtube.com/watch?v=L94qwHUNoUY
It would mean that if you shine a single photon to the beam splitter 4 times consecutively, there's 1/16 chance that all of them will be transmitted. I haven't found something like this being demonstrated in an experiment.
You really have seen the experiment done countless times.
I haven't.

Are you aware of the conservation of energy?
Quote from: hamdani yusuf on 12/07/2021 02:12:39What Is The Nature Of Photons & EM Radiation?As I have stated in my own thread, Is light real, I believe that light is a phenomenon that is produced by the brain of living creatures. Photons and radiation are parcels of energy that travel from their source and land on a detector/converter this is known as the eye. The energy is then received by the brain and perceived as light. My best example of this being true is the fact that when we dream we see light the light in our dreams come from the brain the only instrument capable of producing this vision of light. The skin can feel intense radiation but only the brain its self can see it.
