A`K_(alpha)` X-ray emitted from a sample has an energy of `7.46 ke V. Of which element is the sample made?

If the frequency of k_(alpha) x-ray emitted from the element with atomic number 31 is f, if the frequency of k_(alpha) x-ray emitted from the element with atomic number 51 , is given by 25/x f then x is (assume that screening constant for K_(alpha) is 1)
