Summary:In this Letter the evolution of a single photon and collective effect of a photon system in background plasma waves are uniformly described in the framework of photon dynamics. In a small-amplitude plasma wave the modulation of photon dynamical behavior by the plasma wave can be treated as perturbation, and photon acceleration effect and photon Landau damping are investigated in linear theory. In an arbitrary-amplitude plasma wave, photon evolution trajectories in phase space are obtained by solving dynamical equations, and photon trapping effect and motion equations in the given plasma wave are also discussed. •Photon dynamics in plasma wave are described in Hamiltonian formulation.•Photon frequency shift and Landau damping in plasma wave are discussed.•Photon evolution trajectories in phase space are analyzed.•The trapping condition of photons by large-amplitude plasma wave is discussed.•Motion equations for trapped and untrapped photons are obtained.
