WebThe speed of sound is not constant and depends on the medium where the sound is propagated. In the Earth's atmosphere, if we take into account a temperature of approximately 15 degrees Celsius, the speed of sound is 1225 km/h. This is the reference measure used by the Mach speed, and thus, Mach 1 corresponds to exactly that value. … WebMar 21, 2024 · For example, let’s say it took 2.89 seconds for the 11 claps. To find speed we take the distance, 1000 meters, and divide by the time, 2.89 seconds to get a speed of …
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 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%.
