Bohr's model

  1. Nov 5, 2014 #1
    If the hydrogen gas is supposed to emit photons when the electrons undergo excitation, then why did the gas absorb energy earlier and got the electrons excited?

    Absorption of photons, collisional excitation, etc.

    Electrons absorb photons when excited. Photons are emitted when electrons lose energy.

    The real answer requires QFT and takes into account the quantum vacuum:
