Fresnel Diffraction occurs due to size of the obstruction.Fraunhofer Diffraction is defined as the source of light and the screen in which the pattern of diffraction is obtained effectively at the limitless or infinite distance from the diffracting system.Diffraction is chiefly of two types - Fraunhofer Diffraction and Fresnel Diffraction.Diffraction occurs with all waves which include water waves, sound waves, electromagnetic waves.The phenomena of diffraction can be observed if the size of the opening is relative to the size of the wavelength of light.Diffraction of light is defined as the slight bending of light waves around the border of a slit or an object.Diffraction object gives rise to wavefronts that are also straight or plane.ĭifference between Diffraction and InterferenceĬoherent and Incoherent Addition of Waves. To produce a diffraction pattern, the plane or horizontal wavefront is connected by means of a convex lens.The incident wavefronts on the diffracting obstacle are horizontal or plane.The screen and the source are infinite from each other.The important points for Fraunhofer Diffraction are discussed in the below points: Fraunhofer Diffraction occurs when the distance is increased and the outgoing diffracted wave becomes straight or horizontal. By using a convex lens, the diffraction pattern is obtained. Resolving Power of Microscopes and Telescopesĭiffraction is primarily categorized into two types -įraunhofer Diffraction is defined as the source of light and the screen in which the pattern of diffraction is obtained effectively at the limitless or infinite distance from the diffracting system.
