Interference and diffraction of light are the nature performance of wave character,which is the result of superposition of waves.The essential difference between interference and diffraction phenomena is that interference comes from the superposition by the two or limited interfering beams of light,and diffraction is from the superposition by an infinite beam.From the perspective of optical path difference,corresponding to the same optical path difference,the minimum conditions of single-slit diffraction becomes the maxima conditions of double-slit interference.The reason is that the slot width is so small that can be considered as a single light source under the double-slit case,and the interference in the same slit can be ignored;while the single-slit diffraction minimum conditions are exactly correspond to the interference in the same slit.

Abstract Basic explanations of the double slit diffraction phenomenon include a description of waves that emanate from two slits and interfere. The locations of the interference minima and maxima are determined by the phase difference of the waves. An optical wave, which has a wavelength and propagates a distance accumulates a phase of A matter wave, also having wavelength that propagates the same distance accumulates a phase of which is a factor of two different from the optical case. Nevertheless, in most situations, the phase difference, for interfering matter waves that propagate distances that differ by is approximately which is the same value computed in the optical case. The difference between the matter and optical case hinders conceptual explanations of diffraction from two slits based on the matter–optics analogy. In the following article we provide a path integral description for matter waves with a focus on conceptual explanation. A thought experiment is provided to illustrate the validity range of the approximation .
The double-slit interference experiment has long been regarded as a cornerstone of the wave theory of light. However, optical interference patterns are absent in everyday life, prompting many scientists to question the validity of the experiment under specific conditions. Until now, no experiments have definitively challenged this theory. Here, we revisit double-slit experiment through experimental validation. Results show that light and dark fringes are not caused by light wave interference, but rather by diffraction from vertical walls of the slits. This discovery challenges the conventional wave interference theory and presents a new perspective on the pulse nature of light, where overlapping spectra enhance energy without cancelation. This research offers novel insights into the nature of light and introduces new perspectives for optical research.

Abstract There is a huge difference between the result derived from the principle of light wave interference and the objective fact: (1) the farther the propagation distance is, the larger the light wave, so the larger the light spot should be. (2) Interference only occurs on the way from the double-slit device to the light target. If the distance is longer, there should be more interference points to make the pattern brighter. (3) The stripes along the road are continuously modified by interference, so the pattern obtained by moving the light target should change with the distance. (4) Because the principle is exactly the same, interference stripes should appear at the same time with a dispersive effect. (5) The products of light wave interference should be the new light waves that diffuse around the interference point as the center of the ball. They will not only trigger more interference, but also make the increment mode of light wave form an exponential infinite iterative cycle. This would create a singularity similar to Big Bang. (6) Dark stripes are generated not by sustainable interference but by one-off annihilation. (7) If the light source is replaced by another wave source, the corresponding results cannot be obtained by double-slit, Michelson–Morley and refraction tests. (8) Let alone a photon passing through two slits at once, since the stripes are much fainter than the source, it proves that light cannot pass through any untargeted slits. (9) It is impossible to generate anything from the interference point of size 0. (10) In the causality test, the light that has collapsed into particles should be reapplied to the double slit to verify whether it can produce stripes. (11) If "observation can tamper with results", then this phenomenon is also known through observation, which means that it has been tampered with. (12) As a feature unique to light but not to other forms of waves, the polarization absence interference condition is a major defect. (13) Refraction principle: Similar to driving, the light beam turns to the side that decelerates first. (14) The simplest fundamental principles of optics are reflection and focus, but they are followed by light rather than light waves. (15) The wavelet source principle applies only to water waves but not to light waves. (16) Because the direction of vibration and propagation is orthogonal, the s-wave cannot produce the Doppler effect. The absence of the Doppler effect in binary star systems orbiting each other is an objective astronomical phenomenon, which has been mistaken for hard evidence that the speed of light does not change. This phenomenon proves that the redshift must be a misunderstanding of other astronomical phenomena and that all celestial bodies cannot have direct evidence of the Doppler effect. The absorption spectrum of hydrogen is not radiation, and the redshift data are disputed. Redshift cannot turn light into circular magnetic lines. The gravity provided by dark matter will destroy the solar system. Hubble's law of the absence of redshift is wrong. (17) Secondary light source, barely make light in transparent medium propagation principle can be justified, but not for opaque medium.
