Is it possible to make a light source that shifts waves of light to cause destructive interference to cancel the other light source out to make it fully dark?

in theory yes you can do it. But real word is harsh, the light you see every day is mix of almost all wave lenght so to interfire whit that you would need emiter that send all waves but moved by pi/2 (to make it simple i asume every wave is sinusoidal). It might work at still viev but at dinamic you wolud have to know the future to destroy incomig light. Beside that it will work as long as you stay behind you foton destroyer (sorry for broken eng)
