I haven't been able to find any literature that answers this question in a pleasing way. Also, all sources on the internet are contradictory.
If electromagnetic waves (out of phase since they are emitted by the gaseous atoms in discharge tube) sent through a diffraction gitter interfered with each other there would not be a symmetric interference pattern. When performing some diffraction experiment, a symmetric pattern obviously arises at the screen though. The same frequency is obviously not enough for the waves to interfere, so I wonder:
What are the criteria for electromagnetic waves to interfere with each other? None of my teachers has been able to answer this question properly and I have received the most unreasonable answers you can possably imagine. :p
