1. Patterns with Real Double Slits
Sketch the pattern (I/Im versus angle theta) seen when 500 nm light is shown onto two slits spaced (center-to-center) by 60 µm and having width 20 µm.
(a) First determine where the zeros of the slingle slit pattern would occur; mark these on the graph.
(b) Between the first and second zero, the intensity is about 4% of the peak intensity; mark these points.
(c) Sketch (lightly) the single slit envelope.
(d) Determine the locations of the double slit maxima and mark them.
(e) Sketch the overall pattern from 0 to +3 degrees.
