47. From the data given in the problem, we calculate frequencies (using Eq. 39-1), take their square roots, look up the atomic numbers (see Appendix F), and do a least-squares ±t to ±nd the slope: the result is 5 . 02 × 10 7 with the odd-sounding unit of a square root of a Hertz. We remark that the least squares procedure also returns a value for the y -intercept of this statistically determined “best-±t” line; that

Unformatted text preview: result is negative and would appear on a graph like Fig. 41-17 to be at about . 06 on the vertical axis. Also, we can estimate the slope of the Moseley line shown in Fig. 41-17: (1 . 95 . 50)10 9 Hz 1 / 2 40 11 5 . 10 7 Hz 1 / 2 . These are in agreement with the discussion in 41-10....
