Sound Waves
Sound is a disturbance that travels through a medium as a longitudinal wave. The particles in the medium move back and forth, transferring the energy without moving the particles of the medium along. Sound can travel through gas (air) solid (table) or liquid (water)
Sound travels through air at 343 metres per second.
The speed of sound varies in different materials and at different temperatures.
The quicker the energy is transferred between the particles of the medium, the faster the sound travels. Materials that are more elastic or dense will transmit sound energy faster. More densely packed or freely moving particles will transmit sound faster. Increasing the temperature also increases the speed of sound as the particles in the medium are moving faster as temperature increases.
Sound waves are longitudinal waves, they alternatively compress and rarefy the medium they travel in.
