Photons  

In General > s.a. electromagnetism; history of quantum physics; light; Notoph; photon phenomenology; Wavelets.
* History: Introduced by Planck; Used by Einstein to explain the photoelectric effect; Called "light quantum" until G N Lewis introduced the name "photon" in 1926.
* Evidence: Compton effect; Photoelectric effect (although photons are not necessary if one uses the quantum theory of electrons); More direct evidence is the fact that atoms recoil when emitting radiation.
* Mass bounds: 1975, mphoton < 6 × 10–16 eV/c2, from Jupiter's B field; 1989, mphoton < 6 × 10–16 eV/c2 4 × 10–51 kg, from Earth's B; 1994, mphoton < 3 × 10–27 eV/c2 [?]; 1998, mphoton < 7 × 10–17 eV/c2, from Cavendish balance; Bounds are also obtained from timing of GRB pulses.
