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 Sounds Waves

Concept Builders - Sounds Waves

A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts in Wave Motion and Sound.

Activities

Decibel Scale

🞋︎ Learning Goal: To determine the deciBel rating of a sound if it is known to be so many powers of ten more (or less) intense than another sound with a known deciBel rating.

Name That Harmonic: Closed-End Air Columns

🞋︎ Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.

Name That Harmonic: Strings

🞋︎ Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.

Name That Harmonic: Open-End Air Columns

🞋︎ Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.
