As a result, the vibration of the items induces sound wave compression and refraction. It also causes sound waves to travel across the medium. Some Facts Regarding Compression The gap between particles under compression is shorter than the typical spacing. A longitudinal wave is the zone w...
Waves - Sound This GCSE Physics quiz on waves looks at sound. Sound energy travels as alongitudinal wave. Sound waves travel through a medium in a different way to electromagnetic waves, they requireparticlesto travel across a distance. The particles vibrate in a series ofcompressionsand...
For example, if one whispers on one side of the room, the sound is focused by the elliptical surface and the whisper can be heard at a point on the other side of the room.[2] Refraction “Refraction” of sound is when sound waves change direction because of a change in what they ...
Surface refraction of sound waves affects calibration of three-dimensional ultrasound. Radiat Oncol. 2015;10:119.H. Ballhausen, B. D. Ballhausen, M. Lachaine et al., "Sur- face refraction of sound waves affects calibration of three- dimensional ultrasound," Journal of Radiation Oncology, vol...
sources of sound, the effect of the refraction of sound waves in the sediment layer on the levels and the structure of the sound field formed in the water column at short ranges, namely, in the first geometric shadow zone and in the insonified zone below the channel axis, is considered....
it is defined as the number of refractions and compression which occur per unit time. the frequency is measured in terms of hertz wave velocity – it is the measure, which is used to calculate how fast does the sound wave propagate in the given medium. the unit of wave velocity is ...
Sound waves are generated by any vibrating body. For example, when a violin string vibrates upon being bowed or plucked, its movement in one direction pushes the molecules of the air before it, crowding them together in its path. When it moves back again past its original position and on ...
In physics, sound is characterized as the propagation of mechanical waves through a medium, typically air, liquid, or solid. These waves are generated by vibrations, which cause particles in the medium to oscillate back and forth, creating areas of compression and rarefaction. The speed, frequency...

Sound is a vibration that propagates as an acoustic wave through a medium by means of compression and rarefaction of particles in the medium.
