    1. X-Rays of wavelength of 0.065nm undergo Compton scattering from free electrons in carbon. What is the wavelength of the photons scattered at a 90 degrees relative to the incident beam?




    λ'-λ = (h/mc)(1-cosθ) is the equation I know, but I would really appreciate an explanation of some sort for what each symbol stands for, and and different forms of this question

    λ' : incident wavelength
    h: planck constant
    m: mass
    c: speed of light
    θ: scattering angle
