Homework Statement
I'm a bit confused by this question. It starts off by saying a Cu target emits an x-ray line of wavelength λ=1.54 Angstroms. It then goes and says part A of the problem..
A) Given that the Bragg angle for reflection from the (111) planes in Al is 19.2 degrees, computer the interplanar distance from these planes. Recall that aluminum has an fcc structure.
I don't understand why they start off by telling me about copper and then go onto aluminum in the actual question part... is there a connection that I am missing here?
