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

Sound as a Longitudinal and Pressure Wave Video Tutorial
Many students are troubled by the idea of sound being a wave when there are no crests and troughs. In this Sound as a Pressure Wave Video Tutorial, Mr. H clears up the confusion with a short presentation on why sound can be thought of as a pressure wave. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
Why is a sound wave referred to as a pressure wave?
How are compressions and rarefactions associated with pressure?
Physics Interactives: Simple Wave Simulator
The Simple Wave Simulator provides you a virtual wave machine for exploring the nature of a wave, quantitative relationships between wavelength, frequency and speed, and comparisons between transverse waves such as those traveling through a rope and longitudinal waves such as sound.
Science Reasoning Center, Sound Chapter, Sound as a Pressure Wave
This activity serves as a great introduction to the nature of a sound wave. You will be presented a short (and video-related) reading regarding sound waves. The reading focuses on the pressure oscillations of a sound wave and provides two diagrams and two plots of pressure as a function of time for two different sound sources. The reading is followed with interactive questions. This is a great follow-up.
Physics Interactives. Waves and Sound Section: The Particle Wave
The Particle Wave simulation allows students to explore the nature and properties of a wave. Properties such as wavelength, amplitude, and speed can be changes. The effects of the change on the wave pattern and particle motion can be immediately observed. A Student Activity sheet and a stand-alone Concept Checker accompanies this activity.
Minds On Physics, Sound and Music Module, Mission SM1: Nature of a Sound Wave
Mission SM1 pertains to the fundamental nature of a sound wave. This video and the next video in the Series would provide sufficient background to complete this activity. The mission will provide students a rigorous exercise in close reading, critical thinking, and conceptual reasoning.
