Those novel phenomena: (1) challenge the conventional light wave interpretations of the physical optics, the electromagnetic wave and the quantum probability waves, namely, those interpretations are incomplete; (2) challenging Bohr¡¯s complementarity principle and the wave-particle duality; (3) suggest that it is the photon-photon interaction, instead of the wave-wave interference, that produces the phenomena. To interpret consistently above phenomena is the challenge and demands new theory. https://pubs.sciepub.com/ijp/12/1/4/ijp-12-1-4.pdf double slit cross-double slit single slit cross single slit pattern evolution interference pattern non-interference pattern diffraction pattern non-diffraction pattern interference-embedded-in-diffraction hybrid pattern
