The Compton effect describes the increase in wavelength (and decrease in energy) of a photon when it is scattered. The change in wavelength is given by the Compton wavelength shift formula: Δλ = h/mc (1 - cos θ), where θ is the scattering angle. For backward scattering (θ = 180°), Δλ is maximized, resulting in an increase in wavelength.
