The Physics Of Sound -

) : The maximum displacement of particles from their rest position. It determines ; greater amplitude corresponds to a louder sound. Wavelength (

The speed of sound in a fluid or solid is also determined by the material's bulk modulus ( ) or Young's modulus ( ) and its density ( The Physics of Sound

: Regions where molecules are spread apart, resulting in low pressure. 2. Characteristics of Sound Waves ) : The maximum displacement of particles from
