35	Transmission of Sound Sound travels outwards from its source in the form of sound waves in straight lines. Sound can travel through solids, liquids and gases but cannot travel through a vacuum. Sound travels fastest through a solid because the particles in a solid are very compact. Sound travels at about 300 metres per second through air. Sound from the explosions in the Sun cannot reach us because there is a large vacuum between the Sun and the Earth.
