reciprocal lattice

[jmontgomery@flsouthern.edu]

Question on “Reciprocal Lattice Video”. I am not seeing how the orthorhombic lattice with origin at a lattice point translates to a finite reciprocal lattice. Wouldn’t the lattice point at the origin map to (infinite, infinite)? Furthermore, any point on the x or y axis would also get mapped to infinity on y* and x*. If however the origin is shifted to, say, in the middle of the 4 lattice points that make up a rectangle, then I can see how the points map to a finite area. What am I missing? Does reciprocal lattice depend on choice of origin in direct space?

This question will be addressed in the feedback webinar.

May I please ask whether we can discuss this question in the current academic year as well?
