Wavelength of K(a). X-ray of an element ...

Wavelength of `K_(a)`. X-ray of an element Ais`lambda_(1)` is and wavelength of `K_(a)` X-ray element B is `lambda_(2) (lambda_(1))/(lambda_(2))`is equal to`(1)/(4)` and `Z_(1)` and `Z _(2)`are the atomic numbers of element A and B respectively. Then relation between `Z_(1)` and `Z_(2)` are given by

A

`2Z_(2)-Z_(1)=1`

B

`Z_(2)-2Z_(1)=1`

C

`(Z_(2))/(Z_(1))=4`

D

`(Z_(1))/(Z_(2))=4`
