The Physics Of Sound -

) : The power per unit area, often measured on a logarithmic scale in decibels (dB). 5. Interference and Superposition

: Regions where molecules are spread apart, resulting in low pressure. 2. Characteristics of Sound Waves The Physics of Sound

) : The speed at which the wave travels, which depends on the medium's density and elasticity. In air at 20∘C20 raised to the composed with power C , the speed of sound is approximately 3. The Wave Equation and Speed ) : The power per unit area, often
