![]() The music from the radio can be audible directly in front of the entrance without diffraction. ![]() Diffraction occurs in all waves, not only sound waves. Diffraction is the term for the bending of a wave. If a radio is playing in a house with the entry open, the sound will twist about the surfaces bordering the entrance. A sound wave is unaffected by a barrier the wave just twists about it. Strong (short wavelength) noises always travel farther than cheap (long wavelength) ones. Owl, for example, can converse over great ranges because their long-wavelength guffaws are capable to diffract over forest trees and go further in comparison to the songbirds’ short-wavelength tweets. Several forest-dwelling birds make use of long-wavelength sound waves diffractive capacity. We detect noise diffracting about corners or via door gaps, enabling us to catch others’ noise in neighboring rooms from where others are talking to us. Diffraction of sound about edges or via doorways Other elements, like increased air retention of high frequencies, have a role in the sensation, but diffraction is one of them. Thunder across a long distance will be heard as a low rumbling because the long wavelengths may twist around barriers to reach you. Thunder from a nearby bolt of lightning would sound like a crisp boom, suggesting that there is plenty of large noise present. The difference in sound between a near lightning hit and a far one When one gets visitors, however, guests will be disappointed due to the larger off-axis changes from the little loudspeakers. When any loudspeakers are only for you, one might be delighted with the compact loudspeakers since one can place himself in the optimal listening place. In practice, this confines the audience’s hearing range. So, while you could hear equal sound right on with the speaker, the upper frequencies would fall off quicker in comparison to the low as one moves away from the axis. Send us feedback about these examples.If one constructs tiny and compact speakers, the gap between both the roughly equivalent arrangements of ups and down gets more evident. ![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'diffraction.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Monica Cull, Discover Magazine, 30 Mar. Robert Ross, Robb Report, This means that light passes through the muscle fibers (myosin) and causes diffraction - or the slight bending of light. IEEE Spectrum, 29 July 2023 Wide front baffles are not terribly in vogue at present, and most loudspeakers today employ very narrow front profiles to mitigate diffraction anomalies inherent in mounting a dynamic driver in a cabinet with a wide, flat front. 2023 Overlapping cones of light produce an asymmetric diffraction pattern, resulting in unpleasant imaging effects. 2023 In this image, the Sunrise Arc appears as a red streak just below the diffraction spike at the 5 o’clock position. The Physics Arxiv Blog, Discover Magazine, 29 Nov. 2024 The team then compared the electron diffraction patterns with those theoretically expected and from gold and found close agreement. 2024 Since these mirrors are put together in a hexagon, there are six main diffraction spikes. 2024 However, diffraction effects at the laser wavelengths used to put precise information inside these nanoscale color centers is an obstacle that has limited the amount of data that can be stored within the volume of each color center. Recent Examples on the Web The latest image depicts a brilliant starburst pattern surrounding one of three giant molecular cloud complexes with a series of diffraction spikes.
