An unknown element is used as a target in an x-ray tube. Measurements show that the characteristic spectral lines with the longest wavelengths are 0.155 nm and 0.131 nm. What is the element? (Hint: you will find the answer to Problem 40 to be useful.)

Problem 40

Determine the correct equation to describe the K_α frequencies measured by Moseley. Compare that with Moseley’s equation for K _β frequencies. Does the result agree with the data in Figure 4.19? Explain.
