Ultrasound Primer / Basics
... ultrasound behaves in a similar manner to audible sound, it has a much shorter wavelength. This means it can be reflected off very small surfaces such as defects inside materials. It is this property that makes ultrasound useful for nondestructive testing of materials. ...

Thermodynamic properties of liquid mercury to 520 K and 7 GPa
... For most of its thermodynamic properties liquid mercury can be described, as a simple liquid1 , though it is a very unusual element compared to other close-shell elements. As an example, it is the only metal liquid at ambient conditions, due to relativistic effects on the core electrons2,3 , and it ...

... As this is the total distance that the sound has traveled to the object and back, we must divide by 2 to find the one-way distance. This use of echoes is the basis of sonar (sound navigation and ranging). The pulse of sound that is used should be short, and high frequencies are usually used, as they ...

... From a physical point of view, sound is a travelling wave of compression and rarefaction through a medium (solid, liquid, vapour or plasma). Consider a leaf's rustling being heard by a cat. Four stages of this process can be identified: - generation of sound at the source - transfer of sound through ...

Underwater acoustics
Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water and its boundaries. The water may be in the ocean, a lake or a tank. Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz. The propagation of sound in the ocean at frequencies lower than 10 Hz is usually not possible without penetrating deep into the seabed, whereas frequencies above 1 MHz are rarely used because they are absorbed very quickly. Underwater acoustics is sometimes known as hydroacoustics.The field of underwater acoustics is closely related to a number of other fields of acoustic study, including sonar, transduction, acoustic signal processing, acoustical oceanography, bioacoustics, and physical acoustics.
