Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1660. WebDiffraction is an optical effect which limits the total resolution of your photography — no matter how many megapixels your camera may have. It happens because light begins to disperse or "diffract" when passing …

Experimental results are in good agreement with the theoretical analysis.

Webdiffraction patterns are also observed in th e image plane. In order to generate a pattern, you set the lens against the aperture and simply use the focal length of the lens as the aperture to screen distance (ie replace s with f’) Everything else is the same. Diffraction is another factor that limits the image quality in optical systems.
