I am a sound tech and I no from my work there that if you have (in theory) two sound waves and 1 is 180 degrees out of phase with the other that they will cancel each other out. - This is mainly the basic theory of noise canceling headphones (along with some acoustic material, etc) and balanced mic leads.
But if we model light as waves does that then mean that if there was two identical sources of light (same wave length, amplitude, etc) but one was 180 degrees out of phase with the other would that appear to produce no light at all?
Just a thought, that no one seems to be able to tell me the answer to. Maybe I'm missing some information somewhere along the track.
Any thoughts?
Thanks
