Textbook sections 284 286 Physics 1161 Lecture 21 Recall Interference at least 2 coherent waves Constructive full wavelength difference Destructive ½ wavelength difference. Before the 1950s the prism was the pr imary dispersive element in spectrometer designs The use of an epoxy replication process in the 1950s led to the mass production of plane ruled reflective diffraction gratings New availability of ruled gratings Thought Question. Consider a single slit diffraction pattern. At the first dark fringe above the middle bright fringe, what is the phase difference between the contribution to the field from the topmost and bottommost edges of the slit?. Conflict.  .
