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.

Home Concept Builders Vibrations and Waves Wavelength

Wavelength

The Wavelength Concept Builder is a tool that guides a learner through the meaning of wavelength as the length of the repeating pattern towards being able to calculate the wavelength if given a pattern and the length of the pattern. There are three activities included in this Concept Builder. The first activity - Wave Anatomy - provides the learner practice with identifying crests and troughs in a transverse wave pattern and compressions and rarefactions in a longitudinal wave pattern. In the second activity - Counting Waves - learners must determine the number of waves displayed in a transverse wave pattern. In the third activity - Determining Wavelength - learners calculated the wavelength of a wave when provided a transverse wave pattern and the length of the given pattern. Question-specific help is provided for each of the 12 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.

🚀︎ Launch Concept Builder

Users are encouraged to open the Concept Builder and begin. There is no need for an activity sheet for this Concept Builder.

Learners and Instructors may also be interested in viewing the accompanying Notes page. Technical information, teaching suggestions, and related resources that complement this Interactive are provided on the View Notes.

We now offer a video tailored to this Concept Builder.
