Double Slit Exp: What Really Happened?

Click For Summary
SUMMARY

The discussion centers on the double slit experiment and its implications in quantum mechanics, specifically addressing the quantum eraser experiment. Participants confirm that when detectors are activated, photons exhibit particle-like behavior, hitting two distinct spots on the wall. However, if the data from the detectors is erased before observation, the resulting pattern on the wall resembles a wave pattern, demonstrating the duality of light. This phenomenon underscores the role of observation in quantum mechanics, as detailed in the quantum eraser and delayed choice quantum eraser experiments.

My question is about the double slit experiment..I was just listening to a guy explain this experiment on youtube and I got skeptical at one point in his explanation. He said that when the photons went through the double slits the detectors were turned" on" then the observers viewed the results, seeing which slit each photon went through then observing the wall they hit. The results in this case were that they hit 2 spots on the wall. Then with the detectors still" on" they took the data then erased the data before "looking" at it then looked at the spots on the wall and it resembled a wave pattern? Is this the way the experiment happened or is this guy distorting it somewhat?
