Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Mission SM11 Harmonics for Closed-End Air Columns

Mission SM11 involves the mathematical analysis of closed-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 closed-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 closed-end air column if given the frequency of a harmonic, the wave pattern and the speed of waves in the air.
