The energy ratio of two `k_(alpha)` photons obtined in `x` -ray from two metal targets of atomic numbes, `Z_(1)` and `Z_(2)` is ,

The intensity distribution of X-rays from two Coolidge tubes operated at different voltages V_(1) and V_(2) and using different target materials of atomic numbers Z_(1) and Z_(2) is shown in the figure which one of the following inequalities is true?

The wavelength of the K_(alpha) line of X-ray of an element having atomic number Z=11 is lambda . For which atomic number will the wavelength of that line be 4lambda ?

What is the ratio of frequencies of K_(alpha) -lines in the X-ray spectra of sodium (Z=11) and carbon (Z=6) ?
