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 )

Options

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)`

Answer

A

Explanation

Mosley's law is `f = a(Z - b)^(2)`
