For lines in K series, b=1 (a = 1.042 × 10-2); for lines in L series, its value is more & so on. This relation is known as Moseley's law. Statement: The frequency of a spectral line in the characteristics X-ray spectrum varies directly as the square of the atomic number of the element emitting it.
Today, we know that the atomic number gives the number of protons (positive charges) in the nucleus. This was the discovery made by Henry Gwyn-Jefferies Moseley. He found that certain lines in the X-ray spectrum of each element moved the same amount each time you increased the atomic number by one.
