Find the "Mask Patterns" image in the "DNA diffraction folder;" this is the transparency through which we can shine the laser light. The top row of masks is designated A, B, and C from left to right, and the remaining masks are similarly designated D, E, F (second row) etc. Observe the diffraction patterns produced by masks A, B, and C. 1. Describe how the array of lines in mask A create the corresponding diffraction pattern (e.g. how does the spacing, positioning, and orientation of the lines correspond to the diffraction pattern?). 2. Qualitatively describe how the orientation and spacing of the lines in mask B compare to those in mask A. What effect does this have on the diffraction pattern? 3. Qualitatively describe how the orientation and spacing of the lines in mask C compare to those in mask A. What effect does this have on the diffraction pattern
