There are a few browsers that will show no output whatsoever. Speed of sound in air calculator allows you to calculate speed of sound waves in air at different temperatures in different measurement units. The speed of sound at 20C and high humidity is approx. Most browsers, will display the answers properly but You may change the significant figures displayed by 001 will be displayed in scientific notationĪnd with the same number of significant figures specified.
Calculations are based on the speed of sound at 21C (344 meters per second). If you hear 2 similar sounds in a small interval of time, your brain will hear them as just 1 sound. Numbers larger than 1,000 and smaller than. Corresponding values are calculated while typing. 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. Not see answers such as 77.3333333333333333. The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. Now INPUT the wavelength or frequency >įor easy readability, the answers are displayed in a "significant figure" format so you will However, if you require another speed (for example the speed of sound in air at 15☌), then click on the sixth box (labeled "other") and enter 340.3. Five of the most common speeds are ready to choose by clicking and once chosen, the value in meters per second will be displayed in the box on the right. Sound waves travel about one million times more slowly than light waves but their frequency and wavelength formulas are somewhat similar to light wave formulas.Īs usual, here's a calculator to make the work a little easier for you.įirst, select the speed of sound.
