WebAs you can see from the figure, due to the high frequency oscillations, there are peaks in the amplitude twice as often as peaks in cos 2πν1−ν2 2 t. Thus what we hear are beats at the beat frequency νbeat = ν1−ν2 (13) We use an absolute value since we want a frequency to be positive (it’s the same frequency whether ν1 > ν2 or ... WebThe speed of the standing wave pattern (denoted by the symbol v) is still 640 m/s. Now the wave equation can be used to determine the frequency of the second harmonic (denoted by the symbol f 2 ). speed = frequency • wavelength. frequency = speed/wavelength. f 2 = v / λ 2. f 2 = (640 m/s)/ (0.8 m) f2 = 800 Hz.
