title:  Wave Board 2
aka:  Single slit diffraction pattern.

Description:
Wave trains can be shown coming from different parts of a single slit and interfering constructively and destructively at different angles.

On flip side is a similar model for double slit diffraction.  See Wave Board 1.

Question?
   How different is the path length from each source (in terms of wavelengths) to the points indicated.
