13.2 Wave Properties: Speed, Amplitude, Frequency, and Period

WebSound intensity describes the rate of energy flow through a unit area. In the SI system of units, the unit area is 1 m2. And hence the units for sound intensity are Watts per square meter. Sound intensity also gives a measure of direction as there will be energy flow in some directions but not in others. WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as v w = λ T 13.3 or v w = f λ. 13.4 From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8. WebA sound wave from a police siren has an intensity of 100.0 W/m2 at a certain point; a second sound wave from a nearby ambulance has an intensity level that is 10 dB greater than the police sirens sound wave at the same point.
