Equation of sound wave
WebThe speed of wave is not dependent upon wave properties such as wavelength and frequency. Thus, the speed of the sound wave is 340 m/s for each of the four pipes. For Pipe C, the frequency can be determined from knowledge of the speed and the wavelength using the wave equation: v = f • λ where λ is the wavelength. First, rearrange the equation.
