Angstroms, and from there, atomic bonds can be found. 3) How, in practice, could you use Bragg diffraction to determine the arrangement of atoms in an unknown crystal? Bragg diffraction can be used to compare the unknown interference pattern of one crystalline solid to the known shape of a similar interference pattern. If the unknown crystalline structure of one solid is comparable to that of a known hexagonal structure, then one possibility for the crystal structure is very likely a hexagonal structure. Conclusion Bragg’s Law, equation 8.1, can be verified through this experiment. While minute error can be attributed to incidental table shaking, imprecise 2-4° angle increments, averaging the voltmeter, and non-uniformity within the pseudo-crystalline structure, Bragg’s Law still held true within a reasonable percent error. This experiment aids the scientific community by offering a systematic way to decipher crystalline structures. Appendix d d

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
