Speed of sound - Wikipedia 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 92 s or one mile in 4 69 s
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 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
What is the Speed of Sound? (with pictures) - AllTheScience The speed of sound varies depending on altitude, temperature and the medium through which it travels For example, at sea level in a standard atmosphere, at a temperature of 59-degrees Fahrenheit (15 Celsius), sound travels 761 miles per hour (1,225 km p h)
17. 3: Speed of Sound - Physics LibreTexts The speed of sound can change when sound travels from one medium to another, but the frequency usually remains the same This is similar to the frequency of a wave on a string being equal to the frequency of the force oscillating the string
Speed of Sound Definition - BYJUS The speed of sound is defined as the distance through which a sound wave’s point, such as a compression or a rarefaction, travels per unit of time The speed of sound remains the same for all frequencies in a given medium under the same physical conditions
Physics Tutorial: The Speed of Sound - The Physics Classroom 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
