Physics question compton scattering?

  1. Jul 3, 2013 #1
    1. The problem statement, all variables and given/known data
    The length of the photon waves which are under Compton scattering ( compton scattering is applied on them) is measured in the angle =90 degree.If ΔΛ/Λ is 1.5 %,what is the length of the waves of the falling photons?


    2. Relevant equations

    3. The attempt at a solution

    The only problem here is ΔΛ/Λ = 1.5 %, I dont know how to relate that to the above formula..

    By definition, Δλ = (λ' - λ)/λ.

    I think that should be Δλ = (λ' - λ) or Δλ/λ = (λ' - λ)/λ.
