Rentgen tube, De-Broile wavelength and Compton effect

  1. Mar 27, 2012 #1
    1. The problem statement, all variables and given/known data
    A Roentgen tube produces radiation with minimal wavelength. (λM)
    De-Broglie Wavelength of electrons reaching Anode is λE.
    Assuming electrons are not relativistic, what is the proper relation between wavelengths
    λM, λE and Compton wavelength (λC)


    2. Relevant equations
    λE=h/p
    λC=h/mc
    I am not sure, minimal wavelength - what that is ?
    This is multiple answers question, but any of the answers don't make sense to me.


    3. The attempt at a solution
    I think that relation between λC and λM can be wrote down through Compton effect:
    λC=λE-λM=h/mc(1-cosα)
    However, there is no angle given, so I cam confused about what to do?

    Thank you in advance.
