What do experiments with the transmission of light through holes of various sizes show?

If the hole radius r> √пd, the laws of geometric optics will be fulfilled. Otherwise, an interference pattern will be observed. Moreover, as long as the hole is less than the first Fresnel zone, the illumination will increase, but then the illumination will begin to decrease if the hole radius is greater than the radius of the second Fresnel zone, the illumination will increase again, etc.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
