According to the Moseley's law, the frequency of a spectral line in X-ray spectrum varies as.

Options

A. Atomic number of the element
B. Square of atomic number of the element
C. Square root of atomic number of the element
D. Fourth power of atomic number of the element

Answer

B

Explanation

From Moseley's law ,we get ,
` v=a(z-b)6^(2)`
This equation clearly states that, the frequency of a spectral line as square of atomic number of the element .
