You must learn some of the rules that we will derive for particular crystal structures; one example will be to determine which reflections are allowed for an fcc crystal.
The other lesson is more general and is really concerned with why we have these rules. Why are certain reflections absent or weak and how can you use this information to learn more about your material?
