Electric field in time from two plane wave interference. Red is positive electric field amplitude and blue is negative electric field amplitude. The two waves have slightly different wavelengths and are traveling in nearly the same directions. Nodes (destructive interference) and anti-nodes (constructive interference) are clearly observed as lines in the overlap area. If you look carefully, you can see that the nodes and antinodes are moving.
