Hi, to understand finally the Laue equation for diffraction I am missing something :(adsbygoogle = window.adsbygoogle || []).push({});

h*p+k*q+l*r =integer. Given thatp,q,rare integers how comeh,k,lMUST BE INTEGERS as well?

Sayp=q=r=2, thanh=k=l=1/2works just fine. I understand that there is something about a common multiplier, but what I really want to see is a SOLID MATHEMATICAL proof to that statement. I am not a mathematician but an engineer and have no clue there to start to look for such a proof . . .

help?

Thank you,

Anton
