Q. Mosley measured the frequency $(f)$ of the characteristic$\ X$-rays from many metals of different atomic number $(Z)$ and represented his results by a relation known as Mosley’s law. This law is (a, b are constants)
A) $f = a(Z - b)^{2}$
B) $Z = a(f - b)^{2}$
C) $f^{2} = a(Z - b)$
D) $f = a(Z - b)^{1/2}$
Explanation
(a) Mosley’s law is $f = a(Z - b)^{2}$
