NettetThe fundamental has λ = 4 L, and frequency is related to wavelength and the speed of sound as given by v = f λ. Solving for f in this equation gives f = v λ = v 4 L, where v is the speed of sound in air. Similarly, the first overtone has λ = 4 L / 3 (see Figure 17.22 ), so that f 3 = 3 v 4 L = 3 f 1. NettetThe intensity of a wave is defined as I = P 4πr2 I = P 4 π r 2 . Intensity: Power output per unit area. The standard unit for intensity is Watts per square meters ( W m2) ( W m 2) . …
