Mission SM10: Harmonics for Closed-End Air Columns

Mission SE10 includes questions that target your understanding of closed-end air columns, their harmonic patterns, length-wavelength relationships, and frequency relationships.  The mission consists of 40 questions organized into 9 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 identify the standing wave patterns for closed-end air columns and use them to state the length-wavelength relationships.
• The student should be able to recognize the relationship between the frequencies of the various harmonics for closed-end air columns.

• What is a nodal position on a standing wave pattern?
• How far apart are the nodal positions on a standing wave pattern?
• How can one match the harmonic number to a given standing wave pattern?
• How can the wavelength of a standing wave in a closed-end air column be related to the length of the column?
• How can the frequency of a harmonic be predicted from the knowledge of the frequency of one of the other harmonic patterns?
