The PDB file for Ca2+-bound calmodulin (PDB code 1EXR) was determined from a crystal with unit cell dimensions a = 25.0 Å, b = 29.4 Å, and c = 52.8 Å. The x-ray source had a wavelength of 0.886 Å. Considering only diffraction planes parallel with the b-c plane, i.e. Miller indices (h 0 0), give the diffraction angle for the first and second order reflections.

1a. For diffraction from a single slit, sketch the expected form of the diffraction pattern. 1b. In terms of the width of the slit, a, where would you expect to find the first minimum? As part of your answer consider points of the edge of the slit and in the middle of the slit, and the path difference between light waves originating at each point to a point on the screen that would result in destructive interference. Explain your answer.
