In quantum physics experiments, how is their equipment fine-fingered enough to experiment on individual particles? For example in the double slit experiment, how were they shooting exactly a single electron at a time?
In: Physics
It’s fairly straightforward to calculate how many electrons are being emitted, and you can dial that down to the point where, for example, only one electron is emitted per second on average. So you know that any electron will go through the slits and hit the detector long before another electron is emitted.
