![]() ![]() (Even subatomic particles like neutrons and electrons, which quantum mechanics says also behave like waves, experience diffraction.) Its typically seen when a wave. All waves do this, including light waves, sound waves and water waves. Italian scientist Francesco Maria Grimaldi coined the word "diffraction" and was the first to record accurate observations of the phenomenon in 1660. Diffraction is the bending of waves around obstacles or corners. Since physical objects have wave-like properties, diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves. ![]() Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. Examples For X-rays, the phenomenon of diffractionby crystals was a natural consequence of the idea that X-rays are waves analogous to light and differ from it only by having a smaller wavelength. Diffraction (Physics): Definition, Examples & Patterns Web6 dec. In classical physics, the diffraction phenomenon is described as the interference of waves according the Huygens Fresnel principle. 2021 Diffraction is defined as a process by which light waves break up into dark and. Diffraction Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit.
