Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
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.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
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

The Boundary Behavior of Waves Video Tutorial describes with detail and explains the manner in which waves behave when they reach the end of a medium - whether it be a fixed end, a free end, or a boundary with a second medium. Numerous illustrations and animations are used in the explanations.
The video lesson answers the following questions:
How does a wave behave when it reaches a free or fixed end?
How does a wave behave when it crosses a boundary from one medium into another?
Physics Interactives: Boundary Behavior of Waves
Our interactive simualtions allow you to playfully alter a variable and observe the result in the form of an animation. Ask a question and pursue the answer. This one on boundary behvior provides a great way to learn.
Curriculum Corner: Wave Motion
Try our Curriculum Corner for a Think Sheet or a whole unit of Think Sheets and get your students thinking about waves. If the video is homework; then these are awesome next day starters. This is free curriculum for the taking. And for a few extra bucks, you can obtain the source documents and purchase a license to place them and any deriviative from them on your course management pages; see the Solutions Guide.

Calculator Pad, Vibrations and Waves, Problem Set WM15
Calculator Pad problem sets make for awesome problem-solving practice. They provide problems with random numbers, an answer field, and lots of help. Students enter an answer and have it checked; they can correct it if it's wrong. Problem Set WM15 gives a quantitative spin to the topic of wave behavior.
Physics Classroom Tutorial, Vibrations and Waves Chapter, Lesson 3 - Boundary Behavior
Our written tutorial pages provide a thorough, easy-to-understand, common-sense approach to Physics topics. This particular page addresses the same topics covered in the video. As such, it makes a great reference for a quick check-up or clarification of an idea.
