Mission SM9 Mathematics for Open-End Air Columns
Mission SM9 involves the mathematical analysis of open-end air columns. You will need to compute column 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 open-end air column if given the speed, harmonic number and length of the air column.
- The student should be able to determine the wavelength and the length of an open-end air column if given the frequency of a harmonic, the wave pattern and the speed of waves in the air.
