W : Build on studentsâ knowledge of literary elements by explaining how to draw conclusions, including determining the theme, based on information in folklore. H : Engage students by using the story Goldilocks and the Three Bears to model how to draw conclusions based on text.
For a signal whose fundamental frequency is f, the second harmonic has a frequency 2 f, the third harmonic has a frequency of 3 f, and so on. Let w represent the wavelength of the signal or wave in a specified medium. The second harmonic has a wavelength of w /2, the third harmonic has a wavelength of w /3, and so on.
1. The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency. Similarly, the peaky sinusoid in Fig. 2 has the mathematical equation, y=sin (x) -0.25 sin (3x).his waveform has the same composition as the first waveform, except the third harmonic component is out of phase with the fundamental frequency, as indicated by the negative sign preceding the â0.25 sin (3x)â term. This subtle mathematical difference produces a very different appearance in the waveform.
