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 , the following graph is obtained. The value of 'n' is

Options

  1. A1
  2. B2
  3. C1 2
  4. D3

Correct answer

C. 1 2

Step-by-step solution

The statement of moseley's law is: “The square root of the frequency of the x-ray emitted by an atom is proportional to its atomic number”. v ∝ Z - b So n = 1 2 Moseley is the scientist most directly responsible for realizing that the structure of the atom is key to understanding the elements themselves.
