Mission SM7: Mathematics of String Instruments

Mission SM7 involves the mathematical analysis of string instrument. You will need to compute string length, frequency, wavelength, and speed for a variety of harmonic patterns. The mission consists of 32 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

Learning Outcomes

  • The student should be able to determine the wavelength and frequency of a standing wave in a guitar string if given the speed, harmonic number and length of the string.
  • The student should be able to determine the wavelength and the length of a guitar string if given the frequency of a harmonic, the wave pattern and the speed of waves in the string.
