Bragg's law for determining crystal structure

[@0mon0zz]

This is definitely the BEST description and definition of Bragg's Law I've ever seen! Thank you sooo much for this video your channel is BRILLIANT so underrated, keep it up! Love from Australia :)

@@TaylorSparks Great to hear :) Yes I'm a big fan of the materialism podcast, especially the geopolymers episode! I've listened for a while. I just had a question about deriving the cubic structure d spacing formula. Just trying to work through the logic so I understand it better. If I start with the standard plane: • The plane intersects the axes at x = A, y = B and z = c so it’s (a b c). • Assuming this is a cubic structure then the locations become (a a a) • Taking the reciprocal of these I get (h k l) = ( 1/a 1/a 1/a) which is the miller indices for this plane. How do I go from those Miller indices to the formula which describes the d-spacing (what’s the working in between I’m missing?) i.e. 1/d^2 = (h^2 + k^2 + l^2)/a^2. I’m just trying to derive it from first principles rather than plugging in formulas so I have a better understanding of things. I have tried looking online for the derivation logic but I haven’t found anything good enough, some of it isn’t even English.
