Characteristic Ka X-rays

  1. Sep 27, 2015 #1
    In an experiment one observes the characteristic Ka X-rays of two elements at energies of 6.930 and 7.478 eV. The higher energy line is due to Ni. What element is responsible for the lower energy line?

    Is this homework? Edit: I moved it to the homework section.

    Simply typing the energy into google gave a result within 10 seconds, faster than typing the question here.

    Then you should look up that formula and use it.
