1.	Use Moseley’s law with b=1, if the frequency of the Kα X-ray of Cu(Z=29) is known to be 1.88×1018 Hz, then the frequency of the Kα X-ray of La(Z=57) is 7.52×101x Hz. The value of x is .(Integer only)
Answer» Use Moseley’s law with $b = 1$ , if the frequency of the $K_{α} X-ray$ of $C u (Z = 29)$ is known to be $1.88 \times 10^{18} Hz$ , then the frequency of the $K_{α} X-ray$ of $L a (Z = 57)$ is $7.52 \times 10^{1 x} Hz$ . The value of $x$ is .(Integer only)
