X-ray Diffraction: here's one I prepared earlier
Here in an x-ray diffraction of a sample of LaNi5 that had been oxidised (I think). You can clearly see the Bragg peaks and the angles (2theta) at which they occur.
That was my 3rd yr project. Well, it was actually to figure out what one of the post-grads did to this sample. But I needed to know the structure of normal LaNi5 in order to do that. I can find one of normal LaNi5.

You can try and deduce the crystal structure from that data if you're game...
