Hi all Based on undergraduate feedback, I am really bad at explaining the Ewald sphere.
So I made a thing to help. It's here: http://www.ysbl.york.ac.uk/~cowtan/ewaldapplet/ewaldintro.html It's been done before and done better by others, but this version fits the hole in my course. If it works for you, feel free to use it. I assume that the following prerequisites have already been taught: 1. The Bragg equation, including the diffraction vector S 2. That the diffraction vector is perpendicular to the Bragg planes and its length is reciprocal to the plane spacing. 3. That Miller indices can be used to describe all the possible sets of Bragg planes. 4. That the diffraction vectors corresponding to every possible set of Bragg planes form a reciprocal lattice with orthogonal directions and reciprocal lengths to the crystal lattice.
