A photon with wavelength λ scatters after colliding with a free electron at A, producing a photon with wavelength λ'. Then this photon scatters after colliding with another free electron at B, producing a third photon with wavelength λ'', moving in the opposite direction to the original photon, as shown in the figure below. Determine the value of ∆λ = λ'' - λ.
