In this paper I propose an explanation of the double slit experiment results, considered in a general form, in terms of the Doppler effect, as a consequence of applying the principle of complementarity. It is shown that, if we accept the fact that both particle and wave are manifestations of the same conceptual whole, in the general form of the particle-wave dualism, then the Doppler effect will be a manifestation for both wave and particle, and the double slit experiment will be a qualitative illustration of this fact.

Different types of Young's double-slit experiments contain a significant amount of both particle and wave information running from full-particle to full-wave knowledge depending on the experimental conditions. We study the Young's double-slit interference in resonant Auger scattering from homonuclear diatomic molecules where opposite Doppler shifts for the dissociating atomic slits provide path information. Different quantitative formulation of Bohr's complementarity principle—path information vs interference—is applied to two types of resonant Auger scattering experiments, with fixed-in-space and randomly oriented molecules. Special attention is paid to the orientational dephasing in conventional Auger experiments with randomly oriented molecules. Our quantitative formulation of the complementarity is compared with the formulation made earlier by Greenberger and Yasin [D. M. Greenberger and A. Yasin, ].

Young's 1D-dimension-double-slit experiments represent the basic mystery of quantum world and was extended to which-way-1D-double-slit experiment. To explore the mystery, 2D-cross-double-slit diaphragm have been proposed, which consists of more than one double-slits intersecting to each other at the same spot. In this article, the extended which-way 2D cross-double slit experiments are presented to test the normal interpretation of the which way experiments. The experimental results show that photons passing through the detected double-slit behave as particle, while photons passing through other undetected double-slit(s) distribute as wave in the same experiment with the same diaphragm. Namely the particle nature and wave distribution coexist, which violates Bohr's complementarity principle. It is a challenge to interpret those observations consistently.
