The ratio of wavelength of K _$\infty$ x-ray line for Nb (Z = 41)to that of Ga (Z = 31)is: A)9/16 B)16/9 C)3/4 D)4/3 E)1.15

Question

Quizplus · Accepted Answer

The wavelength of an x-ray line is inversely proportional to the square of the atomic number (Z) of the element. Therefore, the ratio of the wavelengths of the KF1F1F1S1_$\infty$F1F1F10 x-ray line for Nb (Z = 41) to that of Ga (Z = 31) is:λNb/λGa = (ZGa/ZNb)^2 = (31/41)^2 = 9/16
