everyone know double slit experiment. my question is about second experi which chanced physics. how do we send photons one by one. which machine is used for that and can i get it from somewhere thanks for your answers
The source could be turned down low enough so the emmision is practically single photons.As they say in Wikipedia,okay we never know a weak source disseminate how much photon and i think it disseminates millions of it. i am waiting for another answers
http://en.wikipedia.org/wiki/Double-slit_experimentA low-intensity double-slit experiment was first performed by G. Taylor in 1909, by reducing the level of incident light until photon emission/absorption events were mostly nonoverlapping. A double-slit experiment was not performed with anything other than light until 1961, when Clauss Jönsson of the University of Tübingen performed it with electrons. In 2002, Jönsson's double-slit experiment was voted "the most beautiful experiment" by readers of Physics World.
