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

Visible Light and the Eye's Response Video Tutorial
The Eye And Color Video Tutorial describes the wavelength sensitivity of the three color receptors on the eye's retina and discusses how the incident-absorbed-reflected model can be used to explain how the eye-brain system perceives color in objects. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
What are the mechanisms that allow the human eye to see color?
Concept Builder, Light and Color: Color Addition and Subtraction
Our Concept Builders are one of the best things that you can do to solidfy your learning. This one pertains to color addition and subtraction and is a great tool for exercising your understanding of the incident-absorbed-reflected model.
Curriculum Corner, Light and Color: Reflection, Transmission, and Color
Our Curriculum Corner consists of a collection of Think Sheets on narrowed topics. They serve as perfect follow-ups to the videos in our Video Tutorial Series. This one provides students with abundant practice using the incident-absorbed-reflected model of color vision.
Concept Builder, Light and Color: Color Addition and Subtraction
Our Concept Builders are great for putting learning into practice. This one pertains to color addition and subtraction and is a great tool for exercising an understanding of the incident-absorbed-reflected model. It may be a bit early in the learning cycle for the exercise but at some point students will need to practice these ideas.
