    Cuttoff frequwncy for an x-ray tube

    Yes. Thanks for pointing out my stupid mistake :) Sometimes it just takes a fresh set of eyes.

    Cuttoff frequwncy for an x-ray tube

    How would you calculate the cutoff frequency of an x-ray tube operating at 44kV? I am using frequency = work function/h. I have (44000eV x 1.602E-19J)/1.626E-34 but my answer is wrong. I'm thinking that I converted kV to eV incorrectly, but I'm not sure. Thanks.
