Basically, I have to make a ridiculously short presentation on X ray Crystallography on Friday... however, I still do not understand the principles behind it.
From my research so far, I see that X rays are projected from the source (from a cathode to an anode, reflected into plates (of some material - irrelevant because i know up to this point) to make the X-rays travel parallel to each other.
From here, the X rays hit a crystal. This is the section i do not understand.
What makes the X rays deflect? do they hit electrons or nuclei? :S
What makes the patterns that reflect/scatter off from the crystal?
and i understand that they hit different layers of the crystal lattice. how do they get through the first layer? is it just the off chance that they do not hit an electron/nucleus?
lol, I am so lost and have spend the past 3 hours sitting researching but i still do not get it. Any understanding would be greatly appreciated.
Thanks ^^
