Chemistry Question on Classification of elements & periodicity in properties

It is observed that characteristic XX-ray spectra of elements show regularity When frequency to the power " nn " ie vnv^n of XX-rays emitted is plotted against atomic number " ZZ ", following graph is obtained
It is observed that characteristic X-ray spectra of elements show regularity. When frequency to the power " n " i.e. vn of X-rays emitted is plotted against atomic number " Z ", following graph is obtained.

A

2

B

3

C

1

D

12\frac{1}{2}

Answer

12\frac{1}{2}

Explanation

Solution

The correct answer is (D) : 12\frac{1}{2}
According to Henry Moseley vαzb\sqrt{v}​αz−b
So n=12n=\frac{1}{2}
