The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
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 the 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. v = √γRTK M,
21 Ιουλ 2023 · The speed of sound (v), frequency (f), and wavelength (λ) are related by the formula: v = f x λ This relationship holds true for all types of waves, including sound waves.
25 Νοε 2010 · 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.
This speed of sound calculator determines the speed of sound in the air and water. Not everybody knows about the sound speed dependence on the temperature – the higher the air temperature, the faster the sound can propagate.
An approximate formula for the speed of sound through air in standard atmospheric conditions is: Speed of Sound = 331.45 m/s + 0.6 m/s * Deg C. This corresponds to approximately 1100 feet per second, or 750 miles per hour. Refraction of Sound Waves. As we can see from the formula above, the speed of sound differs noticeably with temperature.
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.
