A cold hydrogen atom might have its electron oriented "wrong" magnetically; the electron will "flip its spin" to align its magnetic moment with the proton's B-field . When it does this, the atom (mostly the electron) emits a photon with energy 5.92E6 eV. [ a) calculate this photon's frequency ] b) calculate this photon's momentum [ c) calculate this photon's wavelength ] 6.315 E33 kgm/s 1776 Ns 556 E24 Ns 123.3 E+3 Js/m 0.2842 E15 kgm/s 1.314 E27 Js/m 19.73 E15 kgm/s 3.157 E33 Js/m
