A new discovery in practice

In optical experiments,using red irradiation which is 0.65 µm and has different, aperture such as 0.08mm, 0.2mm, 0.30mmhole gets the different number of rings carefully observing the video and photos can found that the number of rings whose aperture is 0.22mm, 0.30mm,is much larger than that of rings whose aperture is 0.08 in the optical there fore. The experimental fact that the aperture is hundreds or thousands of times longer than the wavelength of light waves by rough estimation is not consistent with the traditional theory that diffraction occurs only when the aperture is close to the wavelength. Obviously, the current wave optics theory has encountered difficulties, but challenges and opportunities coexist, which is a general rule of scientific development. Perhaps the real wave theory, the "wave-particle" theory, is waiting for us to rethink and re-explore.
