Moseley's equation is represented as √v=a(Z−b) where a and b are constants If OA=1, then atomic number of the elements showing frequency of 400Hz is?
Though Moseley's equation √v taken y - axis and Z on x-axis,if a straight line is obtained at angle of 45∘ and y intercept equal to 1 is obtained when the frequency is 25 sec−1 .Then ,atomic number of the element is
