Suppose an obstacle is placed between the light source and the viewing screen, there will be bright areas and dark areas on the viewing screen, And the boundaries of these areas are not sharp, a complex pattern of light and dark. In classical physics, waves propagate to varying degrees after passing through obstacles such as slits, holes, or disks. Under the right circumstances, any wave has the inherent property of diffraction. However, the degree to which the waves are diffracted varies in different situations. If the obstacle has many densely distributed pores, it will cause a more complicated diffraction intensity distribution pattern.
