Interesting comment indeed.

You can't unless you introduce a "distracting" element in the experiment. Remember that whatever you migh do to "measure" the status of a photon [light] in the wave, you'll produce changes in the original system. The only evidence we could show as proof is the instantaneous collapsing of both waves and the burst of energy at the point of interception.

Two normal light-waves "collide" in space and nothing happens. The very reason light has been classified among the "bosons"... right? "They can occupy the same locale simultaneously." We know that two electrons [with different quantum status (numbers)] can NOT be in the same place at the same time. That's why they are named "fermions."

So... How could anyone explained that after two light waves intercept no one proceeds with their original propagation leaving a busrt of energy instead?

Is this enough to answer your question?
