<h3>What is speed of sound?</h3>
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. The speed of sound in an ideal gas depends only on its temperature and composition. The speed of sound in mathematical notation is conventionally represented by 'c'. The speed of sound is variable and depends on the properties of the substance through which the wave is travelling.
