Speed of sound - Wikipedia 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 92 s or one mile in 4 69 s It depends strongly on temperature as well as the medium through which a sound wave is propagating
Speed of sound | Description Examples | Britannica speed of sound, speed at which sound waves propagate through different materials In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331 29 metres (1,086 9 feet) per second
Speed of Sound in Physics - Science Notes and Projects 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?
Speed of Sound Calculator Check with our speed of sound calculator how the speed of sound in water or air changes with temperature
Physics Tutorial: The Speed of Sound The speed of a sound wave refers to how fast a sound wave is passed from particle to particle through a medium The speed of a sound wave in air depends upon the properties of the air - primarily the temperature Sound travels faster in solids than it does in liquids; sound travels slowest in gases such as air
17. 3: Speed of Sound - Physics LibreTexts Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength You can observe direct evidence of the speed of sound while watching a fireworks display (Figure 17 3 1 17 3 1)
Speed of Sound - Physics Book Speed of Sound 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 In different mediums (gas, solids, or liquids) the speed of sound is different than 343 2 m s
Speed of Sound Sound travels approximately 1 5 of a mile per second or 1 mile in 5 seconds That converts to about 1 3 of a kilometer per second So if you see the lightning 3 seconds before you hear it, the strike is approximately 0 6 miles, or 1 kilometer away Sound travels at different speeds, depending on the medium and the temperature
Speed of Sound - HyperPhysics The speed of sound in air and other gases, liquids, and solids is predictable from their density and elastic properties of the media (bulk modulus) In a volume medium the wave speed takes the general form This agrees well with the measured speed of sound in water, 1482 m s at 20°C
Speed of Sound: A Guide to Understanding and Measuring Acoustic . . . The speed of sound depends on the properties of the medium through which it travels In this article, we will explore the factors influencing the speed of sound in different media, as well as the methods used to measure it, and its applications in engineering
