Was the Young two slit experiment misinterpreted about light?

Question

The effect of the 2 slit experiment can also be explain by particle. The particle would create the same interference distribution as if it was awave as well. Did any thinking scientist ever realize that?

Some scientists are jumping to conclusion about mass particle motion. they forgot that particles masses collide and bounce. This effect in the 2 slit experiment has been totally negleted.What happened to common sense?

Answer 1

No, there would be no interference pattern if light were behaving strictly as a particle. If light acted only as a particle, the pattern seen behind two slits would be the superposition of the patterns seen behind two single slits. That is, if light acted only as a particle, then you should see the same pattern whether you let light pass through two slits for five minutes, or whether you opened only one slit for five minutes, then closed that slit and opened the other for five minutes.

Opening one slit at a time produces no interference pattern, leaving both slits open produces an interference pattern. This cannot be explained by assuming a strictly particle interpretation of light.

Comment on "Additional Details #1"

Particles of light have never been observed to bounce from one another. Quantum electrodynamics predicts that they should, but the effect is so slight, and the probability so low, that there has never to my knowledge been a successful measurement of photon-photon scattering in the laboratory. If the interference patterns in a Young's two-slit apparatus were to be explained by particles of light bouncing off one another, it would imply that light scatters from light very, very easily. Crossing two flashlight beams would produce a diffuse glow from the area of intersection, and the beams would not continue onward to the places they were pointed. We don't see that happening. Another example: if somebody is driving toward you with their headlights on, you cannot reduce the amount of light hitting your eyes by shining your headlights at them and deflecting their beam.
