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 Frequency versus Period Video Tutorial explains the meaning of the concepts of frequency and period and applies them to wave motion. The formulas for calculating frequency and period are presented and two example calculations are performed.
The video lesson answers the following questions:
What is the meaning of the terms frequency and period and how are they related?
Physics Interactives: Waves and Sound - Simple Wave Simulator
A simulation provides a phun, interactive way to explore a topic. That's what you'll find on this page. Spend some time changing variables and observing the result. Also observe the transverse (waves in a rope) and longitudinal (sound waves in air) options. After playing, check your understanding with our Concept Checker.
Calculator Pad, Vibrations and Waves, Problem Set WM1
Calculator Pad problem sets make for awesome practice. They provide problems with random numbers, an answer field, and lots of help. Enter an answer and check it; correct it if its wrong. Problem Set WM1 is all about frequency and period calculations. Tap one of the Help links if you're having trouble.
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.
Physics Interactives: Waves and Sound - Simple Wave Simulator
This is a very popular simulation and one worth using with your classes. It comes with a classroom-ready student activity sheet. And don't forget the Concept Checker as a follow-up. Between our video, our simulations, and you're usual engaging labs, you're going to have some awesome lesson plans.
Physics Interactives: Waves and Sound - Vibrating Mass on a Spring
This simultation pertains more to simple harmonic motion than it does to wave motion. But it comes with a classroom-ready activity sheet that is all about the concepts of frequency and period. It may be what you're looking for.
Calculator Pad, Vibrations and Waves, Problem Set WM1
Calculator Pad problem sets make for awesome practice. They provide problems with random numbers, an answer field, and lots of help. Students enter an answer and check it. They can correct it if it's wrong. This set of problems focuses on frequency and period calculations.
