The virtual double-slit experiment to High School level (Part I): behavior classical analysis (with bullets and waves) and development of computational software

Abstract

This paper analyses the double-slit virtual experiment and it composed of two parts: The part I covers the classical theory (with bullets and waves) and the part II covers the interference with electrons or photons. Firstly, we have analyzed the same experiment that shoots a stream of bullets. In front of the gun we have a wall that has in it two holes just big enough to let a bullet through. Beyond the wall is a backstop (say a thick wall of wood) which will absorb the bullets when they hit it. In this case, the probabilities just add together. The effect with both holes open is the sum of effects with each holes open alone. We have shown it for high school level. Next, we have analyzed a same experiment with water waves. The intensity observed when both holes are open is certainly not the sum of the intensity of the wave from hole 1 (which we find by measuring when hole 2 is blocked off) and the intensity of the wave form hole 2 (seen when hole 1 is blocked). Finally, we have shown a software developed by students about double-slit experiment with bullets.
