Vedclass · Answer

(C) Moseley's law states that the frequency $
u$ of a characteristic $X$-ray line is related to the atomic number $Z$ of the target element by the formula: $
u = a(Z - b)^2$.Here,$a$ and $b$ are constants that depend on the specific spectral line (e.g.,$K_{\alpha}, K_{\beta}$).This law demonstrates that the frequency of characteristic $X$-rays is directly proportional to the square of the atomic number of the target material,rather than its atomic weight or density.Therefore,the correct option is $(c)$.

Moseley's law relates the frequencies of line $X$-rays with the following characteristics of the target element:
