JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
It is observed that characteristic X-ray spectra of elements show regularity. When frequency to the power ' \(n\) ' i.e. \(v^{ n }\) of X-rays emitted is plotted against atomic number ' \(Z\) ', following graph is obtained. The value of ' \(n\) ' is
- A \(1\)
- B \(2\)
- C \(0.5\)
- D \(3\)
Answer & Solution
Correct Answer
(C) \(0.5\)
Step-by-step Solution
Detailed explanation
According to Henry Moseley \(\sqrt{v}\,\alpha z - b\) So \(n =\frac{1}{2}\)
