Double-slit interference has made physics think for 215 years and there is no end in sight. Quantum mechanics always explains it by an interference of 2 waves. A new model of a volatile temporary Association Interaction has now been proposed, in which the particle wave interacts with the electromagnetic wave fields of the surface atoms and their shell electrons. It can be understood as interference between these two wave functions involved or as a deflection of the moving particle from its momentum direction by a quantized angular amount. The quantization of the angle results from the assumption that there are only standing EM waves, so that wave peaks only have certain locations that are periodically spaced. As a result, they are the points of separation for the volatile associated particles. This means that previous interpretations of 'pilot waves' and the like are no longer exclusive. The same Cinematic Association Interaction is generalized to all optical effects, such as transparency, dispersion, diffraction, reflection, opacity and colour formation, but also impacts of particles and absorption. Waves as particles must no longer be thought capable of deleting each others masses and energy, which was a paradox phenomenon of wave interference theories. Compton effect and impacts of particles are identified as a reflection due to same electromagnetic Association Interaction.
