EM Diffraction. As applied to proteins. Diffraction from a grating. Molecular Expressions. Bragg’s Law. N = 2d ∙ sin ( Ө )/ λ Derivation: http://www.eserc.stonybrook.edu/ProjectJava/Bragg/ Applies to electron diffraction from crystals
As applied to proteins
We can model any function by adding together waves that are integral multiples in frequency
F(x) = C0 + ∑Cncos(2πx/(λ/n) +αn).

Note that because this is a 2-Dimensional crystal, you are sampling the continuous Fourier transform in the third dimension.
