Structure Of Atom Question 1
Question 1 - 24 January - Shift 1
It is observed that characteristic X-ray spectra of elements show regularity. When frequency to the power ’ $n$ ’ i.e. $v^{\text{n }}$ of X-rays emitted is plotted against atomic number ’ $Z$ ‘, following graph is obtained.
The value of ’ $n$ ’ is
(1) 1
(2) 2
(3) $\frac{1}{2}$
(4) 3
Show Answer
Answer: (3)
Solution:
Formula: Henry Moseley Equation
According to Henry Moseley $\sqrt{v} \alpha z-b$
So $n=\frac{1}{2}$
