Fraunhofer diffraction

Fraunhofer diffraction is a phenomenon that occurs when light passes through a narrow opening or around an object and creates a pattern of light and dark regions on a screen. This effect happens when the light waves spread out after passing the opening, similar to ripples in water. The resulting pattern depends on the shape and size of the opening or object. Fraunhofer diffraction is important in various fields including optics, photography, and telecommunications, as it helps scientists and engineers understand how light behaves and how to manipulate it for different technologies.
