The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. 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.
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.
Learning Objectives. Explain the relationship between wavelength and frequency of sound. 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.
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.
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 de jun. de 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.
