Jun 17, 2023 · 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.
The speed of sound varies greatly depending upon the medium it is traveling through. The speed of sound in a medium is determined by a combination of the medium’s rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound.
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, 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. The speed of sound in liquid water at 8 °C (46 °F) is about 1,439 metres (4,721 feet) per second.
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.
We can find the speed of sound by looking at the speed of this compressed region as it travels through the medium. In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. We can also watch the speed of sound of a repeating simple harmonic wave.
Dec 5, 2015 · 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.
