I blew away my original OP so now I have rebuilt this OP.
https://micro.magnet.fsu.edu/primer/...cleorwave.htmlThe exact nature of visible light is a mystery that has puzzled man for centuries. Greek scientists from the ancient Pythagorean discipline postulated that every visible object emits a steady stream of particles, while Aristotle concluded that light travels in a manner similar to waves in the ocean. Even though these ideas have undergone numerous modifications and a significant degree of evolution over the past 20 centuries, the essence of the dispute established by the Greek philosophers remains to this day.

To cut to the chase, an individual photon cannot be observed acting as both a pure particle and wave at the same time. But if you assemble a group of many different photons, you can observe some acting like particles and others acting like waves. Many stories did not make this clear.
