If we are studying FCC in the direct lattice, Why does the length of the cube side in the reciprocal lattice equal to 4*Pi/a Where a is the lattice constant,
a*=|G|=2*Pi/a Sqrt(4) = 4*Pi/a
Where a* is the length of the cube site in reciprocal lattice
Note: this thing is repeated in 2 problems and i wouldn't be able to know the reason.
Prefessor is writing it like this but i can't understand (LOL, he also doesn't know to answer me when i asked him, he's just reading from papers, Silliy Professors)
Any one can explain? thanks
