Crystal Diffraction: The Mystery of (1 1 1) Plane in Lattice SC, BCC, and FCC

[dirac68]

Hi, this is my first post.
I have a problem to solve:

"Given the plane (1 1 1) of 3 lattice sc, bcc and fcc, says in which case there is diffraction"

I hope that someone helps me...
Thanks for helpers

You have to calculate the structure factor of the (111) for the 3 structures. The one(s) with non-zero structure factors will produce diffraction a line.

A plane will always give rise to diffraction, irrespective of the type of lattice.

Yes, it's right. I found the solution! Thank you!
