According to Moseley's law , the frequency (v) of the `K_(a)`line and the atomic number Z of the element have the relation (A and B are constants)

Options

A. `((v))/((Z-A))=B`
B. `(sqrtv)/((Z-A))=B`
C. v(Z-A)=B
D. `v(Z-A)^(2)=B`

Answer

B

Explanation

The simplified formula for Moseley 's law is given as ,
`sqrtV=B=(Z-A)implies sqrt(v)/(Z-A)=B`
Where .
v- Frequency of `k _(o)` line
Z- Atomic number of elements
