The 18 pages that link to Sound speed, each with the reason it gives.
Shock waveRelated: A shock's defining motion is faster than this local signal speed.
DetonationRelated: Sonic conditions in the products define the ideal Chapman–Jouguet state.
AcousticsRelated: It links frequency and wavelength and varies with the medium's properties.
SoundRelated: Propagation speed varies with the medium and helps determine wavelength.
Compressible flowRelated: It sets the reference speed for judging compressibility effects.
Bulk modulusRelated: In fluids, it depends on bulk modulus and density.
CompressibilityRelated: For a fluid, sound speed depends on density and adiabatic compressibility.
PhotoevaporationRelated: The heated gas’s sound speed helps set the outflow’s characteristic speed.
Metre per secondRelated: Sound propagation rates are commonly stated in metres per second.
