In the explanations of the double slit experiment it is usually assumed that the superposition of the diffracted waves by two separate slits (one open and another closed) is the same as superimposing the diffracted waves when both slits are open at the same time. This nave use of the superposition principle is generally not valid in either classical electromagnetism or quantum mechanics. As we will see, the diffraction diagram of one of the slits is altered when the other is open and when the slits are closer, the interaction between them is greater. In this work we will analyse the interaction between different types of sources (antennas, loudspeakers and, of course, slits) and we will show how this interaction explains the apparent anomalies in energy conservation and also the recent results of Young’s interference that show that the total diffracted intensity is reduced or increased depending on the distance between the slits. We also make a brief comment on the contributions of our work to the supposed looped trajectories of energy in interference phenomena.

在对双缝实验的解释中，通常假设两个单独的缝（一个打开，另一个关闭）的衍射波叠加与两个缝同时打开时的衍射波叠加相同。这种对叠加原理的简单使用在经典电磁学或量子力学中通常都是无效的。正如我们将看到的，当另一个狭缝打开时，其中一个狭缝的衍射图会发生变化，当狭缝更近时，它们之间的相互作用更大。在这项工作中，我们将分析不同类型源（天线、扬声器，当然还有 狭缝），我们将展示这种相互作用如何解释能量守恒的明显异常以及杨氏干涉的最新结果，这些结果表明总衍射强度根据狭缝之间的距离而减少或增加。我们还简要评论了我们的工作对干涉现象中假定的循环能量轨迹的贡献。
