An element of atomic number 9 emits K_(alpha) X-ray of wavelength lamda . Find the atomic number of the element which emits K_(alpha) X-ray of wavelength 4lamda .

Atomic number of anti cathode material in an X- ray tube is 41. Wavelength of K_(a) X-ray produced in the tube is

When the voltage applied to an X-ray tube increased from V_(1)=15.5kV to V_(2)=31kV the wavelength interval between the K_(alpha) line and the cut-off wavelength of te continuous X-ray spectrum increases by a factor of 1.3 . If te atomic number of the element of the target is z. Then the value of (z)/(13) will be: (take hc=1240eVnm and R=1xx(10^(7))/(m))
