26 de abr. de 2024 · Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties.

In classical physics, the diffraction phenomenon is described by the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets. The characteristic bending pattern is most pronounced when a wave from a coherent source (such as a laser) encounters a slit/aperture that is ...
The definition of diffraction is the spreading of waves as they pass through or around an obstacle. More specifically when applied to light, diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light’s wavelength.
In summary, diffraction is a fundamental phenomenon in the behavior of electromagnetic waves that occurs when they encounter obstacles or apertures. It is crucial for understanding various wave patterns and has applications in a wide range of fields, from optics and spectroscopy to radio communication. Next Article.
The bending of a wave around the edges of an opening or an obstacle is called diffraction. Diffraction is a wave characteristic that occurs for all types of waves. If diffraction is observed for a phenomenon, it is evidence that the phenomenon is produced by waves.
The Diffraction Phenomenon. 🔗. Imagine shining a monochromatic light through a narrow hole of width a little larger than the wavelength. Rather than a simple shadow behind the hole, you will find that there is an interference pattern even though there is aparently only one source of light. This is illustrated in the diagram given in Figure ...
Diffraction is a phenomenon all wave types can experience. It is explained by the Huygens-Fresnel Principle, and the principal of superposition of waves. The former states that every point on a wavefront is a source of wavelets.
