Nature of Sound

Sound

• A source of energy that causes a medium to vibrate

• A disturbance that travels through a medium as a longitudinal wave

• A disturbance that travels through a medium as a surface wave

• A disturbance that depends on the frequency of the pitch

• A disturbance that causes energy to move from place to place
