When a metal of atomic number Z is used as the target in a Coolidge tu

1.	When a metal of atomic number Z is used as the target in a Coolidge tube, let ν be the frequency of the Kα line. Corresponding values of Z and ν are known for a number of metals. Which of the following plots will give a straight line?(a) ν against Z (b) 1/ν against Z(c) √ν against Z(d) ν against √Z
Answer» Correct Answer is: (c) √ν against Z From Moseley’s law, √ν = a(Z - b), where a and b are constants.
