> Light is considered a particle - or more accurately has particle-like behaviours in certain contexts - because you can count individual photon So how do they produce an inference pattern in the double slit experiment? I know you don't have an answer to that, but that's rather the point - neither does QM. Probability density does not explain an interference pattern. Only one thing does - that light is in fact a wave.
