for the following question:(adsbygoogle = window.adsbygoogle || []).push({});

x-rays scattered by a crystal are assumed to undergo no change in wavelength. show that this assumption is reasonable by calculating the compton wavelength of a Na atom and comparing it with the typical x-ray wavelength of 0.1nm.

my problems:

1) why doesn't x-rays undergo any change in the first place?

2) the question doesn't give you an angle, so won't there be 2 variables in

the compton effect equation?
