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.
Learn what is the speed of sound, how it varies depending on temperature and medium, and how it relates to the Doppler effect. Find out the modern value for the speed of sound in dry air and in liquid water, and see examples of sound waves and Doppler shifts.
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. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.

Learn how sound waves travel and how the speed of sound depends on the medium and frequency. Watch a video and answer questions about sound, amplitude, wavelength, and more.
La velocidad del sonido en el aire y otros gases, líquidos, y sólidos se puede predecir de su densidad, y de las propiedades elásticas del medio ( módulo de compresibilidad ). En un medio de volumen, la velocidad de la onda toma la forma general. Esto concuerda bien con la velocidad del sonido medida en el agua, 1482 m/s, a 20°C. La ...
Transcripción del video. si dejamos que un altavoz haga una breve ráfaga crearemos una onda de pulso podemos encontrar la rapidez del sonido observando la rapidez de esta región comprimida a medida que viaja a través del medio en aire no húmedo a 20 grados celsius la rapidez del sonido es de aproximadamente 343 metros por segundo o 767 ...
