I … WebJan 30, 2024 · Modern technology allows the emission and detection of single photons. In an experiment conducted by Philippe Grangier, a single photon is passed through a double slit. The photon then is detected on the other side of the slits. Across a large sample size, a trend in the final position of the photons can be determined. WebOne way of measuring single photons is to use a photomultiplier tube. Photons incident on the tube create an avalanche of electrons in each stage that can be detected as a current pulse. Photomultiplier tubes have sufficiently high gain to detect a single incident photon. daily allowance of students
