There are two mathematical procedures, Fourier-transformation and Convolution, which will be used occasionally in different parts of this course. Let's try to understand how they work.

There are two approaches which can explain the origin of X-ray diffraction: an easy one and the correct one. We will go through each of them.

Interestingly, but usually when dealing with X-ray diffraction we actually mean powder X-ray diffraction which in contrast to single-crystal diffraction is less informative but not that demanding in terms of sample preparation and that's why so widely used.

Now let's learn how to extract structural information from powder X-ray diffraction. We will start with simple manual analysis and then proceed with specialized software.
