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.
The higher harmonic standing waves are called overtones. The second harmonic overtone can be easily heard on a guitar by laying your finger lightly on the string at the midpoint between the two frets after the string has been plucked. If you do this, you hear a faint, higher frequency tone.
