WebBoth these waves travel at different speeds in different mediums. The speed of sound in air is around 761 miles per hour or 343 meters per second. However, this speed is measured at 20 0 C. Other than this, the speed of sound in the Vacuum is 0. This is because of the absence of a medium. The speed of sound in water is about 1500 meters per second. WebSound is a longitudinal wave, which means that the vibration of the air is in the direction of travel of the sound wave. Sound is invisible, so we have to animate to see it. (For film clips of visible examples, see Travelling Waves ). In the animation below, the top graph shows a sine wave y (x'), where x' is a coordinate moving with the wave.
