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)
- f = a (Z – b)2
- Z = a (f – b)2
- f2 = a (Z – b)
- f = a (Z – b)1/2
Answer
(A) f = a (Z – b) 2
