Speed of sound - Wikipedia
The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "swiftness". For fluids in general, the speed of sound c is given by the Newton–Laplace equation: =, where
17.3: Speed of Sound - Physics LibreTexts
In an ideal gas (see The Kinetic Theory of Gases), the equation for the speed of sound is. v = √γRTK M, where γ is the adiabatic index, R = 8.31 J/mol • K is the gas constant, T K is the absolute temperature in kelvins, and M is the molecular mass. In general, the more rigid (or less compressible) the medium, the faster the speed of sound.
Speed of Sound - Equations - The Engineering ToolBox
2010年11月25日 · Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. A disturbance introduced in some point of a substance - solid or fluid - will propagate through the substance as a wave with a finite velocity. The velocity at which a small disturbance will propagate through the medium is called Acoustic Velocity or Speed of Sound.
17.2 Speed of Sound - University Physics Volume 1 - OpenStax
In a fluid, the speed of sound depends on the bulk modulus and the density, v = B ρ. The speed of sound in a solid depends on the Young’s modulus of the medium and the density, v = Y ρ. In an ideal gas (see The Kinetic Theory of Gases), the equation for the speed of sound is.
Speed of Sound in Physics - Science Notes and Projects
2023年6月17日 · In physics, the speed of sound is the distance traveled per unit of time by a sound wave through a medium. It is highest for stiff solids and lowest for gases. There is no sound or speed of sound in a vacuum because sound (unlike light) requires a medium in order to propogate. What Is the Speed of Sound?
17.2: Speed of Sound, Frequency, and Wavelength
Describe the relationship between the speed of sound, its frequency, and its wavelength. Describe the effects on the speed of sound as it travels through various media. Describe the effects of temperature on the speed of sound. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.
17.2 Speed of Sound – University Physics Volume 1
Determine the speed of sound in different media; Derive the equation for the speed of sound in air; Determine the speed of sound in air for a given temperature
Physics Tutorial: The Speed of Sound - The Physics Classroom
At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: v = 331 m/s + (0.6 m/s/C)•T where T is the temperature of the air in degrees Celsius.

2015年12月5日 · The speed of sound is the distance traveled over time by a sound wave in an elastic medium. The SI unit of speed is meters per second or (m/s). The speed of sound in dry air at 20 ° C is 343.2 m/s.
Speed of Sound - HyperPhysics
the speed of sound is v sound = m/s = ft/s = mi/hr. It is interesting to compare this speed with the speed of molecules as a result of their thermal energy. For the specific example of dry air at 20°C, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu.
