I have just seen a photograph known as a Laue photograph. I am reading about the Laue method of X-ray Diffraction. This method is supposed to be useful for determining the orientation of a crystal, according to Ashcroft. My question is how? Orientation with regards to what? It seems to me the concept of orientation is a bit trivial, unless you define a reference or axis, so how is this method helpful?
Thanks.
Thanks.
