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. It depends strongly on temperature as well as the medium through which a sound wave is propagating.
12 wrz 2022 · For air at sea level, the speed of sound is given by \[v = 331\; m/s \sqrt{1 + \frac{T_{C}}{273 °C}} = 331\; m/s \sqrt{\frac{T_{K}}{273\; K}} \label{17.7}\] where the temperature in the first equation (denoted as T C ) is in degrees Celsius and the temperature in the second equation (denoted as T K ) is in kelvins.
13 maj 2021 · The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed. The ratio of the aircraft's speed to the speed of sound affects the forces on the aircraft.
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.
25 lip 2024 · 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.
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.
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.
