"WebFraunhofer diffraction is relevant when considering the far field, i.e., diffraction patterns far away from the refracting structure; this regime is characterized by values of the Fresnel number well below 1. On the other hand, the concept of Fresnel diffraction with large Fresnel numbers can be applied to cases where the near field is relevant. " - Fraunhofer diffraction equation

In spite of the various approximations which were made in arriving at the formula, it is adequate to describe the majority of problems in instrumental optics. This is mainly because the wavelength of light is much smaller than the dimensions of any obstacles encountered.

WebAnd a formula for max/min: x m a x / m i n ( m) = λ L ( L − y) y ( m + 3 4) where even m are maxima and odd m are minima. y is the distance of the light source to the edge and L is the distance of light source to the screen. For infinite y and L (sunlight, for instance), only the L − y = D distance from the edge to the screen matters, and ...

When a beam of light is partly blocked by an obstacle, some of the light is scattered around the object, light and dark bands are often seen at the edge of the shadow – this effect is known as diffraction.
