## Math Solution of Sound

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. Math Solution of Sound Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can…

## Speed Of Sound

Speed 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 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer…
