The revised Photon partition hypothesis is set out. Providing a physical embodiment of wave-particle existence. Three experiments are described: Young’s double slit experiment on light, the Elitzur-Vaidman bomb thought experiment, a variation without a bomb but a path blocking light detector. A quantum physics description of how each experiments outcome happens is given. For comparison the photon partition hypothesis is used to describe how the results come about. An experiment is described and illustrated that may provide evidence that ordinary measurable photons are not fundamental/ indivisible particles. Arrangements of Mach-Zehnder Interferometer apparatus are proposed for the investigation. Division at a half silvered mirror, into a part still detectable as a photon particle, the cut photon body, and a wave-like sub photon companion is hypothesized. Three possible outcomes are described. Two of them support the notion of actual physical photon divisibility. One of the outcomes is not supportive of the notion but could be indicating division of the photon from a usually accompanying environmental effect. Several models of photon divisibility are considered. Some supplementary experiments are given for further investigation according to the outcomes found. Method for ‘interrogating’ photons to ascertain more about their nature is set out. A clearer understanding of the physical nature of photons and its demonstration will be achieved. Concluding: This may help scientists decide on photon partition; if it fits the evidence and in which way it happens.
