The standard interpretation of Young’s double slit experiment is that the light behaves as waves before and after passing through the diaphragm of the double slit. There is one primary maximum intensity at the central position of the interference pattern. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories that distribute as waves. In this article, we place the photon chamber near the diaphragm of the double slit.
The Experiments show: (1) at approximate up to 150 mm range from the diaphragm, there are two primary maximum intensities (Figure on the left), which violates the standard wave interpretations (Figure on the right); (2) the light beams behave as photons.
