A) \[f\propto \sqrt{Z}\]
B) \[f\propto {{Z}^{2}}\]
C) \[f\propto Z\]
D) \[f\propto {{Z}^{3/2}}\]
Correct Answer: B
Solution :
Moseley?s law is an empirical law concerning the characteristic electromagnetic spectrum that is absorbed or emitted by atoms. Using X-ray diffraction techniques Moseley found that most intense short wavelength line in the X- ray spectrum of a particular element is related to the element?s atomic number Z as follows: \[f=(2.48\times 1{{0}^{15}}){{(Z-1)}^{2}}\,Hz\] \[\Rightarrow \,\,\,\,\,\,\,\,f\propto {{Z}^{2}}\]You need to login to perform this action.
