4-67. In the scattering of x-rays from a crystal of NaCl, it is assumed that the scattered x-rays undergo no change in wavelength. Show that this is a reasonable assumption by calculating the order of magnitude of the Compton wavelength for a sodium atom and a chlorine atom and comparing it with a typical x-ray wavelength of 0.10 nm.
