The bremsstrahlung x-ray spectrum of both Moand W cut off (have zero intensity) at about 0.035 nm. X rays with this wavelength are produced by the target element when bombarding electrons are promptly stopped in a single collision and give up all their energy in the form of EM waves. Confirm that electrons having energies of 35,000 eV will produce x ray photons with wavelengths near 0.035nm by this process.
