Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing. Sound also travels through plasma. Sound Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids … Read more

Last Updated: September 23, 2018 at 6:48 pmSpeed Of Sound The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one … Read more
